General Holosun pistol optic thread

[GJM]

While we have had a variety of threads on aspects of Holosun pistol optics, I don’t believe we have a general Holosun thread, so I thought we should start one given their increasing popularity.

Historically, my sense is nearly 20 percent of Holosun optics fail out of the box or in the first few days of use, but if they get by that, they hold up reasonably well. Recently, I bought three 507 V2 units, and while two worked fine out of the box, the third had a problem with the “+” button that controls intensity. Need to send it back. Also, last week a one year old original 507 failed while I was dry firing it. Dot went intermittent, even though the battery tested at 90 percent good.

The 508T and 509T look interesting, and have received positive initial reviews by Sage Dynamics.

Add your experiences with Holosun pistol optics here so we can get a large sample of experiences.

I've had a Holosun 407C on my P80 build since October of last year. It is attached to an RMR-inletted Brownells slide. I've run a few hundred rounds through it (more than 300, less than 500) without any problems. I'm probably going to move it to my 625 next.

My v1 507c has been my duty optic for about the last year. Thousands of rounds down range. No issues. The buttons don’t bother me really. I changed the battery recently just because I felt like it. That would be my only real complaint with it, but the v2 fixes that.

[CCT125US]

My first Holosun HS403GL had to go back. Dot would not adjust, and then would jump to position after several rounds. It's replacement has been working fine, and I would buy another.

[miller_man]

Don't have any holosun's yet so no reports. Been seriously toying with trying one out, waiting for the 508t to become available. But if Holosun can clamp down on their quality control, I think they would give Trijicon a huge run for their money. Would like to see them make different size dots available.

[cornstalker]

In three 407c's and one 508T, the only issue I had so far was the oblongish and off-center 32 moa reticle on the 508T. Holosun replaced it and it looks the same. I have since found several reviews that indicate that it is just the way they are. Easy fix, switch to the 2 moa dot.

I haven't kept any long enough to run up high round counts. Unfortunately, I have been platform-hopping and have let the optics go with the guns when they went.
The 407c on my practice gun was used when I bought it. Unknown round count. The 508T on my carry gun sees little use. It sits at 695 rounds. I may switch both over to HE509T's when they are available due to the lint bucket effect with the open emitter design.

407k on backorder at Midway. When it comes in I will be shipping the 43x off for milling.

[MD7305]

I bought a 507c V1 last fall for a backup pistol optic to my then primary RMR. Over several months shooting with it I've developed a preference for the 507c over the RMR. I can't really put my finger on why, I just like it more. Maybe it's because the window seems slightly larger than the RMR's, the reticle/dot seems crisper (I have a mild astigmatism), and the price. I think I'm at about 3000rds with no issues, swapped between 3 pistols and my CZ Scorpion. It's even taken an unintentional 4ft drop test onto my concrete basement floor after a clumsy drop out of my safe resulting in a small crack that appears to be a shadow in the edge of the window. Zero didn't move, no signs of damage to the body of the sight. I was impressed by that.
My only real "complaints" are that I wish Holosun offered a larger MOA dot option and the logos on the 407/507 seem huge and bright. I subdued mine with a Sharpie. Overall, I'm very satisfied with mine and when I'm ready to purchase another pistol RDS it will be a Holosun, probably a 509T when available.

[Shadow]

T&E'd two HE508T's for my agency about a year ago for 45 days. Shot the heck out of them in different weather and lighting conditions. Both optics passed without a single issue. Purchased my own HE508T which has 5,300 rounds on it without issue and two 507v2's which are at about the 3,000 round mark each and they are strong performers also. Had a number of coworkers and friends purchase HE508t and 507v2s since the initial T&E and not one issue on any of them so far.

[Olim9]

Have a 407C that went 3,500rds with no issues but the brightness adjustment button fell off from a lot of one handed malfunction clearances I was doing. I need to send it out, it’s a great optic

[SteveB]

So far, with a sample size of 4, I’ve been running 50%. An 510C-GR for my PCC arrived completely dead; it’s replacement has been great. I then got a 507-C V2 which arrived with a weird fuzzy distortion in the center of the lens, not usable. Sent it back and it’s replacement is good; sharp reticle, no distortion.

[backtrail540]

With enough going back for replacement, is their warranty service pretty easy to deal with?

My vortex viper warranty was easy peasy and a model for others to live up to.

I have a combined 5000, or so, through two 407c’s, including a couple classes with no issues.

For my non-duty purposes, I prefer it in pretty much every way to the RMR.

Working now. Looks great, thanks for putting that together. A nice and concise reference.

[awp_101]

Great list, thanks!

[bruceride]

I have 2 510Cs and a 407 V2 that I don't have a pile of rounds thru. But they all zeroed nicely and seem nicely put together. Time will tell on durability.

[breakingtime91]

The new thin holosun seems like a really good option for guns like the 43x and 48

[DMCutter]

I have a 507c V1 on a 229. It started shutting off after a couple of rounds when I had a few hundred total rounds through it, but I put in a fresh battery and several hundred rounds later the issue has not recurred. I haven't dropped it or done one handed manipulations with it so I can't address its ruggedness.

[TAZ]

I have a 507c v1 riding a Brownells slide closing on 1k rounds. O issues aside from a crappy battery from the factory. The circle dot reticle is ever slightly canted, but not enough to bother me.

Also own one of their rifle RDS 503 something or another. No issues there either, but it’s on a low use carbine for my son.

I’m eagerly waiting fir the 407k series to become available. My G48 needs an optic.

[mrozowjj]

I have 5 of the 407CO models with the 8 MOA ring.

My one serious use pistol has a Trijicon RMR 6.5 MOA dot and I had previously a used Vortex Venom 6 MOA dots as my budget option on a few pistols and a Ruger PCC but after buying one of the 407CO models to test out I found it so intuitive to use those were all pulled, sold, and replaced with these 407co.

I don't have a bunch of rounds on the guns themselves as I did this swap around Dec/Jan and then by March my range shut down so I haven't been able to shoot in months. They hold a zero and seem to work pretty well at least as well as the Vortex Venoms that they replaced.

I leave most of them "on" in the shake awake mode so I'm curious how long those batteries are going to last but that is a really nice feature. It's super handy to know that my CZ Scorpion and Glock 45 I have setup for USPSA are always ready. Even though I said I still use the RMR for any serious use this feature makes the RMR feel behind the times.

[noguns]

I have a 508 v1 on an MOS with ch precision plate. Only 855 rounds fired. No issues. If not for covid I'd probably have a few thousand rounds on it. I can't decide between auto mode with ring and dot mode or 2 moa on setting 9 all the time. I wish you could manually set the brightness AND use solar at the same time. It gets really bright under the sun when on Auto.

[Bratch]

I’m holding out for one for the 365XL. I received an in stock notice from Osage for a Romeo0 and didn’t even click on it after deciding the Holosun would be a better bet.

Can someone share the model number of the referenced "thin" Holosun optic? I am suffering "number confusion" with the Holosun products!

[noguns]

407k and 507k are both new and thin. The difference is that the 407k is 6moa only and the 507k has the 32moa ring and/or 2moa dot.

[GJM]

The option of just a 32 moa ring is the magic of Holosun optics.

Perfect shotgun optic IMO.

[Rick R]

Perfect shotgun optic IMO.

I just ordered a mount to try my 507c on my Stoeger M3K. I’ve been using a Vortex Venom on it. I want to see if the 32MOA ring is more better. If I like it I may need a 507c V2 for my G19

FWIW Showing up to shoot sporting clays with a 10 round semi auto equipped with a RDS will bring out the Fudd in your father-in-law. :D

[Trukinjp13]

508t v2 is looking very tempting for my mos pistol. Waiting to find one in stock. Had a rmr 2 that worked perfectly for me but this seems like for the money and the reviews it may be gtg.

Is there any reason not to put a 507k on a G19 instead of the 507C V2?

[stomridertx]

Since the 19 slide is wider, might as well have a larger window and go with the 507c. Also, if it's not a MOS 19 then the RMR footprint would be better to have on that gun to be a little more future proof. I'm excited about the 507k because I carry a G48 daily.

Moved to the 407K vs. 507K thread

[Up1911Fan]

I would welcome any further comments or details that George or any other forum member might wish to add regarding opinions of the Holosun 407K vs. the Holosun 507K mounted on a carry gun like the Sig P365XL.

My optic experience on pistols is limited, with some experience with the Leupold DPP, the Trijicon RMR, and most recently, the Trijicon SRO. My personal preference among these three optics (all on "game guns" )is the SRO with a 5 MOA dot. The primary reason for this preference is the window size of the SRO, combined with the fact that so far I have encountered virtually zero issues with "finding the dot" in the SRO, even when shooting from awkward positions, WHO, SHO, etc. That was not the case with the DPP and RMR.

Considering the significantly smaller window of the mini Holosun optics, "losing the dot" may be a potential problem on a carry gun, so I am looking for every advantage I might gain by picking the Holosun that gives me the best chance to acquire and maintain visual contact of the dot. So . . . . 407K or 507K, and why?
I'm waiting on a 407K, I wanted the bigger dot and have no interest in the circle.

Aaron Cowan seems to be liking the 507K so far

[HCountyGuy]

So everything I’ve found online about the 507C (https://amzn.to/3e6JHw6) says it has a 2 MOA dot with 32 MOA circle.

Did I get a misprint on my box?

55914

[DaBigBR]

Checked all of my 507 boxes and they say 65.

That's amusing.

[entropy]

Sooo....tell me more about this “circle” that I have toggled thru and never used. I am “reticle curious”....

[DaBigBR]

I've been a little slow to post in this thread because I usually post on my phone and wanted a chance to sit at an actual keyboard and talk about these sights.

I'm a very small time FFL, but I sell a fair amount of pistol red dots. I started looking at Holosun a few years ago when Travis Haley started speaking positively of some of their products for rifles (think T1 sized optics). When the 507C, 407C, and 508T showed up and got some good coverage from Aaron Cowan and Steve Fisher, I decided to give them a chance, especially after checking out a Nighthawk of Fisher's that had a 508T. I ended up owning a 2011 and a 507C within a week. That led to a second one on a Glock 26 with Brownells slide. After shooting them a fair amount, I started selling them. I would guess I've sold a few dozen - mostly 507Cs in red, a few in green, and a couple 508Ts and 407Cs. To my knowledge there has been ONE failure among these optics, many of which went to cops with a large PD in the southwest, and that was handled basically immediately by Holosun sending out a new sight, rather than waiting for the user to send it in.

I have found that I greatly prefer the "dot only" configuration. The circle-dot seems like a good idea, but in practice, I found it to be crowded. It is arguably faster to acquire if you are still trying to learn the system, but I just can't get on board with it. The dots have all been very crisp for me, which is saying something as I have a mild astigmatism. I really like the 2 MOA dot over my 3.25 MOA RMRs, so much so that I've picked up a 1.0 MOA RMR to try out (because: snobbery). I cannot prove or disprove Holosun's battery life claims as my two demo 507Cs were replaced when the V2 came out. Both were still on the original battery and were sent to new owners with brand new batteries. They had about a year on them.

Downsides? The biggest one to me is that I want the dot to be a little brighter on max brightness. This is only an issue in direct, bright sunlight. It's not even really an issue, I just notice that the RMR goes quite a bit brighter and aids some in faster shooting in high sunlight conditions. The buttons on the V1 were not the best in size or tactility, but I would go as far as to say that the V2 buttons are BETTER than the RMR's buttons. Probably the best micro red dot controls on the market. Not sure that that really means anything in the real world, but they are nice.

I have recently acquired a couple green dots and am excited to give them a shot. Just handling them, my impression is that the green appears brighter to my eyes in sunlight, possibly fixing the brightness shortfall mentioned above. I hope to do some testing starting this week. More to come, hopefully.

[Grey]

So I am totally confused, what is the difference between a HE508T, 508T v2? Looking for a new pistol red dot to get back into the pond.

The V2 has a side loading battery and bigger buttons. HE508T has to come off to change the battery.

[cornstalker]

Oh, and the housing has a more square profile on the V2.

Thanks man, the wait begins for the V2.

[noguns]

Anyone carry appendix with a 509t? I'm having a hard time deciding if a closed emitter will be worth printing more. Just guessing because my 508t prints just enough to make me conscious about it VS no rds. Apparently I have to use a holster with no wing with my RDS pistol.
Not much price difference between a 508t or 509t. Also the AOS has a package deal with holosun 507-509, FYI.

[gruntjim]

I just got in my 407 green dot. I had also ordered the CHPWS V4 unit.

It had everything I needed, including V3.

I can't wait to take it out and zero it, since it's as solid a unit as I've ever seen.

I am not surprised. It held zero, and it had no trouble putting three rounds in the same hole at ten meters.

The Holosun seems like a solid buy.

I won't really know until I can do a class with it, but who knows when that will be available.

Hosted the Sig Pistol Mounted Red Dot Instructor Class at my agencies range a couple of weeks ago. Prior to class my 508t had 5300 rounds on it without issue. The second day of class was held in a tropical storm the east coast got hit by. Heavy rain and high winds made the day interesting. The 508t ran flawlessly through another 850 rounds as did 3 other Holosun's in class. Only issue was a little surface rust on the mounting screws the next day.

I have not had a chance to shoot it yet, but in dry fire I really like it and the features it has. Trying to decide on whether I keep it on the Glock and put my RMR on my 1911 or vis a versa.

Interested in your thoughts. Just picked up another G5 G19 MOS and have the CHPWS plate waiting. Was going to go with another RMR but this will strictly be a training gun so was considering the 407 or 508 V2 instead.

Ran my 407c v2 (https://www.amazon.com/HOLOSUN-HS407C-V2-Classic-Red-Sight/dp/B084WHQ84Q/) for the first time today. I ended up taking it off auto brightness, as it just wasn't adequate for my eyes in a variety of light conditions.

It held up for 150 rounds today. I wasn't sure about the qc since it didn't come with a battery tray but they sent me one and all seems good so far. I'll post if it has any issues.

[MDFA]

Up front I'll say again that this is without a range session.

I prefer the mount it once and done, rather than removing it to change the battery as with the RMR. Also the battery tray eliminates the need for the RMR sealing plate to get a good battery connection and to seal the bottom of the unit against moisture.

I found the auto brightness feature to work well inside my home while moving from room to room with varying light conditions. It seemed to react instantly from a brightly lit to a dimly lighted area. I only tried it indoors (keeps the neighbors from getting nervous).

I found the 2 moa dot to bloom less than the 3.25 moa dot on my RMR with my astigmatism. I had the dot set to setting 6. I like the shake awake feature. It also seems the the slight upward curve of the lens housing allows me to find the dot quicker during presentation.



Hope this helps.

[mrozowjj]

Holosun has a new optic with a chevron and a 250 MOA circle. I believe the intention of the circle is to help tell you where the center of the optic is. Personally I can take or leave the giant circle but a giant chevron like that is my dream reticle for a rifle so I am stoked. I just wish they'd put it in their 503 tube or 512 or even the 508 so I could get something enclosed to throw on a rifle

Tried that, their chevron is entirely too small in that one so it just looks like a oval blob to me; virtually unusable without a magnifier. This one has a much larger chevron unless that camera is lying.

I think you are correct on that. It is 10MOA which is pretty big.

Sent out my V1 407C for repairs because the brightness button fell off from too much one handed racking, got the optic back today and to my surprise, there was a new box with a brand new V2 407 in it.

Free of charge. I really like Holosun.

I'm about to try this red dot pistol thing for the first time and just ordered at Glock Gen5 19 MOS. I'm going to purchase a Holosun HS407C v2. I'm going to order Torx alloy steel mounting screws from McMaster Carr, can someone confirm the screw size to mount to the Glock MOS plate? Battlewerx sells 6-32 Thread Size, 5/16" Long for the V1, is there a difference in screw size for the V2?

Supposedly the screws are different between V1 and V2, though I'm not specifically sure how. When I installed the Forward Controls Design plate, they advised using the short screws which come with the Holosun. They are T10 torx head 6-32, not sure of the length.

Thanks for the info. I might try reaching out to Holosun. I've had really good luck with a bunch of Holosun optics, but I have had a cross bolt fail in one of their mounts. I'd feel better if I could replace the included screws with some known quality fasteners. If anyone has a V2 and can measure the screws I'd greatly appreciate it.

Thanks for the info. I might try reaching out to Holosun. I've had really good luck with a bunch of Holosun optics, but I have had a cross bolt fail in one of their mounts. I'd feel better if I could replace the included screws with some known quality fasteners. If anyone has a V2 and can measure the screws I'd greatly appreciate it.

I'd do it for you but mine are currently all screwed into MOS plates (which reminds me, I should probably get some spares). If you happen to find out this info, would you mind sharing?

I definitely will. I checked the downloadable manual but no joy there, it just says "there are screws". I'm going to call them tomorrow morning. Worst case, I'll measure the ones it comes with when I get the optic and post here. Maybe the screws it comes with are just fine and I'm overthinking this, but a pack of 100 quality fasteners from McMaster is under $10 and cheap insurance.

[HeavyDuty]

I don’t know if this is the best place for this question, but searching for “BLPS” didn’t turn up anything even though I know it’s come up before.

Has there been any more info about this prototype low profile sight? I think the concept shows tremendous promise, being an ultra low profile direct mount MOS sight suitable for CC.

I'm about to try this red dot pistol thing for the first time and just ordered at Glock Gen5 19 MOS. I'm going to purchase a Holosun HS407C v2. I'm going to order Torx alloy steel mounting screws from McMaster Carr, can someone confirm the screw size to mount to the Glock MOS plate? Battlewerx sells 6-32 Thread Size, 5/16" Long for the V1, is there a difference in screw size for the V2?

I haven't heard back on the email I sent, but I think this might be a case for common sense and deductive reasoning. Battlewerx sells 6-32 x 5/16 for the V1, and there is only one size smaller you can go in 6-32 and that's 1/4. So it has to be 6-32 x 1/4 if shorter screws are needed. I think the wise thing is to order both and see which works better, and also some M3 x 0.50 mm Thread Size, 6 mm Long for screwing the plate to the slide. Since I'm going to use the stock MOS system at first and the weak point is the screws, I want the best screws possible. If I wind up falling in love with the setup I'll get the FCD plate.
This is my order, this would cover every Holosun pistol optic to the Glock MOS. I may wait until I hear back from Holosun before hitting the order button and eliminate the length I don't need to save a little money.
*EDIT the 1/4" length fasteners will not work, they are too short.

My 407co v2 arrived. The auto sucked for me so I switched to manual like my 407c v2 but otherwise it seems like a nice reticle. It will be a bit before I get any info on it as I need to send my slide to get milled. But the 8 moa circle is nice and round, though without correction to my vision it looks like a giant dot rather than a circle with nothing in the middle.

Would you mind measuring the length of the short screws that came with your optic and post here? It would be a huge help, mine doesn't arrive for a week and I'd like to get McMaster fasteners en route.

[stomridertx]

Just got off the phone with Holosun support. The screws provided with the V2 pistol optics are as follows:
Long screws for picatinny mount: 6-32 x 3/8"
Short screws: 6-32 x 9/32"
He said the short screws are the correct length for the MOS plate, but some customers have had to file them down. Here's the kicker, McMaster Carr does not have a 6-32 x 9/32 black oxide Torx alloy steel fastener available. They only have 1/4" and 5/16" lengths, and 9/32" is in between.
*Edit
1/4" Screws are too short and I wound up using the Holosun provided screws. I did not need to file them as they stop just short of the bottom of the plate. The McMaster Carr 1/4" screws I got measured a bit shorter than 1/4", so I'm thinking the 5/16" length is the right screw to get, and be prepared to possibly have to file them. I can find no source for a 9/32" length torx fastener that is made of alloy steel. There appears to be nothing wrong with the Holosun provided screws, but I think it's worthwhile to source a box of quality fasteners if fielding these optics.

Interesting. Sounds like they felt the Trijicon lawsuit was unwinnable and are giving up that fight.

I hope the new button location is as ergonomic and durable as the V2 buttons. I could see them rushing something through without doing a lot of testing.

Question for the experienced RDS users. Just ordered my first RDS pistol, LTT 92 RDO. Provided that works out well, I will be sending my current slide for milling.

Given the pending redesign, would you just wait for the newer model with the thought that if I end up with multiple RDS having a “standard” button layout would be beneficial.

Or grab one of the current models understanding that future models will likely have a different button layout?

More likely trying to make sure they can keep selling stuff if Trijicon receives an injunction to prevent Holosun from selling the disputed products. I suspect you will see the new 1632 battery and the old buttons.

How's this for bad luck:
I got my new HS407V2 in on Friday. I took it to the range Saturday and finally figured out how to bench rest my Glock 19.5 MOS enough to get a good 25 yard zero. Super happy with myself, I left the gun on the sandbag rest while looking through my spotting scope, bumped the table, and the pistol took a Sage Dynamics style fall to the concrete optic first. I got the same result he did as well, glass cracked in the upper right corner. It held it's zero, is fully functional, and I don't even notice the crack when presenting. That left me all weekend to wonder if Holosun would cover this under warranty or tell me I need to be more careful and to piss off. I called them today, and the rep on the phone was nice and said it was covered and directed me to the online RMA process. Here's hoping it's painless, but so far so good. Now that I've experienced the worst case scenario first hand and it was still functional, I'm confident enough to carry one. However, if this return doesn't go smoothly I may think twice before getting another one. How much y'all wanna bet I wind up with the X2 version with "new" buttons shaped like Trijicon's tears?

[DaBigBR]

Holosun's warranty process is painless and smooth. I had a coworker leave his new 19 MOS and new 507C V2 (fortunately unloaded) on the roof of his car and drive off, causing is to fall onto concrete at residential street speed. Same result: delamination in the corner, held zero, still worked. Holosun sent him a replacement and he returned his. This was July-ish.

My hope is that they take this lawsuit as an opportunity to put all of their optics on the 509 (ACRO ripoff) mounting pattern. That would allow both tubular and reflex options on the same pattern, with an inherently superior mounting system, and they can use whatever buttons they want. My suspicion is they were planning to do this eventually anyway as evidenced by using the side loading battery compartment on all models.

[DaBigBR]

That's not happening.

The change is to the buttons and not to the footprint.

[Whirlwind06]

I have 2 HS407A3 I bought them from PSA early this year. They are no-frills shake awake 3 MOA dots with the battery on the bottom. They were fairly inexpensive I got them as a way to get into using dots.

One is on my EDC g19.3 with Lone Wolff slide, round count ~500. Put in a new battery when I mounted it and no problems so far.

The second one has been on a g34.5 MOS that my match gun. Round count ~2500, I’ve had problems with the MOS mount but the dot has been fine.

I just purchased 2 507C one for the 34 and the second for g45 the I had milled. I plan on the g45 to be my EDC.

Right now I will say it's smooth but not painless. They sent me a pre-paid shipping label in one email to send mine back, and a tracking number in another email for my replacement. I sent my optic in the next day with that label and tracking showed they received it 5 days later. I let a week pass with no status on the tracking number that they had shipped me anything and emailed them for an update. They told me that the optic received from me was, quoted from the email, "on day one of the 10-12 business day inspection process. When the inspection is completed they will send a replacement if it was found defective, or return yours if it was not defective." Uh-oh. I would hope that it doesn't take 10 days to spot the damn crack in the glass. I'm guessing from that statement that I'm in for about a 2-3 week wait. I'm guessing I have Covid to thank for this.
My takeaway is if you are running a Holosun optic that is functional but needs warranty work, order another one and don't send the broken one in until you have a replacement. That puts you in RMR money, but it's not like no one has ever had to warranty an RMR so the same logic applies there.

I ran a 509T (LE T&E) at a Steve Fisher Class a week ago. I got the unit on a Monday, mounted it and roughly sighted it in on Tuesday and shot it that Friday. I liked it a lot. It has a slight magnification to my eye but after shooting it all day that disappeared. Steve helped me finalize a zero and was able to do a 97 on his 25yard aggregate test. I like the window size as well as the size of the actual unit. We shot probably around 500-600 rounds or less so not a high count but I really like it over the other units we have tested. Those include the DPP, RMR and ACRO. Next favorite for actual use would be the ACRO. The RMR I didn't like at all and the DPP has an odd dot to my eyes. The 509T had a clear clean dot for me, though I'm not a fan yet of the eotech style reticle. That one is too busy for my simple brain at this point. I ran the dot all the time and shot well with it. I'll be interested to get everyone's take when they start getting out into the wild. Our agency is testing units for possible approval and the 509 is the favorite among instructors who have shot them all.

[DaBigBR]

How does the 509T mount? Initial stuff talked about it coming with an MOS plate but the press stuff says "RMR adapter."

Hoping these will be in the wild soon. I saw that C&H will get their first shipment on Monday.

How'd you like the class? I did one last year and found it very thought provoking. I shot a 94 with the Novaks on my GRP Recon .45.

[cpd2110]

I enjoyed it. It was my first rds handgun course and as I stated before I have had limited exposure and was honestly unsure if this was a good idea for officers. Steve is a good instructor but I wasn't sure what to expect based on some instagram live feeds where he kind of trashes rds specific classes. I think he undersells the class and he did a nice job of pointing out issues that LE needs to be aware of, this was nice as I was the only LEO in the class. He had several ways to get guys up to speed a little quicker, transition concerns and other nuggets. I took notes as the day went along and probably have 6-7 pages worth. This was a good primer for me as the head firearms instructor. I came away convinced we can do this but also convinced we need to walk into it cautiously and that our instructors need a specific course for them. I will give props to Steve, as he comes off angry at times online. I thought he was very approachable in class, held everyones attention and due to only having 6 people everyone got specific one on one instruction. He helped every shooter in someway and everyone but me had been to a rds specific course previously. I would definitely recommend him. I've been to a whose who of tactical/firearms instructors and he held his own in terms of teaching within his knowledge base, logical progression of the class, ability to diagnose shooter issues and help correct them. He also did something I haven't seen before but liked a lot. After every section of the class we did an AAR/what did you learn. Every shooter was asked and given the opportunity. Questions were raised and he would address them logically, provide a demo example and then ensure your question was answered to your satisfaction. In a large class this might be time consuming but in ours it was appreciated by each student. He was also aware that many of the shooters had limited ammo, so it wasn't an ammo count class where you just shoot to shoot. He was deliberate in his round count and managed shooter fatigue as well. There was a ton of 25yard shooting which as you know can be taxing. it was a good 8 hours and well worth the money.

Hoping these will be in the wild soon. I saw that C&H will get their first shipment on Monday.

We mounted our T&E on the C&H plate. It was rock solid, I initially thought at times it was on there a little crooked but Steve said he thought the same thing when he started. I screwed up the directions on zero'ing but he squared me away and once there I believe I took the top gun on the 25 yard 10 round slow fire drill we did to end the day. C&H was awesome to deal with as well when I ordered. I told them I needed the plate quickly as when we got the notice for the 509 being shipped it was just a few days before the class. C&H shipped it quickly, I not only got multiple emails but also a text that the order was received, mailed and a tracking number. I had a question upon receipt and the owner responded with a text. I don't know how long they can do that as they grow but I couldn't of been more impressed, customer service goes a long way with me and they knocked it out of the park. We plan to make C&H plates a requirement for any future rds program for our agency. The MOS plates were okay, but none sat flat on the gun when mounted, one was bent and we just never had any confidence in them. The C&H plate for the 509 was an easy install and like I said it feels like its part of the gun and not an add on. I'd buy with confidence.

[Dr. No]

My 509T just arrived this week and I mounted it up on a MOS with the CHPWS plate as well. Very slick. I'm very impressed with the form factor, features, battery tray. If they have the battery life right it will be an Acro killer. My only "complaint" is the buttons are not as nice to adjust as the Acro, but otherwise it's pretty cool.

One other thing we've noticed that is odd - the front glass is slanted back toward the shooter and this causes some distortion with the image you see through the sight. I'm going to get to shoot some 25y stuff with it next week, but it is distracting.

That's a necessity with red dot sights. Here's an excerpt from Holosun's FAQ:
"Why is my front (objective) lens canted (angled)?
A canted objective lens is part of the design of a reflective/reflex sight. The objective lens must be canted to properly reflect the dot/reticle back to the user's eye."

Neither the rmr nor the acro have this distortion issue, so no it is not part of a reflex sight design. It is part of the Holosun design, but whether it is truly detrimental remains to be seen.

It's part of the reflex sight design. When the T-2 and MRO's came out, the same question would always pop up on forums about the canted front lens. Aimpoint even addresses it on their FAQ for the MRO. Another reason for the perceived distortion is that Holosun's aren't a true 1x.

Maybe I'm arguing semantics here, but the correct phrasing would be "It is part of *some* reflex sight designs". C-more, acro, rmr, deltapoint, I could go on .... none of them use a canted lens.

IMO, as I have run a T2 as my primary optic on my duty rifle for the better part of 5 years, there is little to no distortion noticeable through that optic. Everyone that has picked up the 509T has commented on the distortion, so it seems to be a bit more prevalent.

Is the "distortion" the magnification, about 1.1x? Holosuns do have that IME, but I dont think it has anything to do with the lens angle.

If so, I think you will find your brain creates a composite image when actually shooting with both eyes open, and the distortion will not be noticeable when shooting. The only exception may be precision shooting with one eye closed. If that is the case, my suggestion would be to always have both eyes open and use a target focus, regardless of shot difficulty.

Actually, all of them, including your T2 use a lens that is angled (canted). It is a necessary element of the collimating mirror design. Some may have a visual distortion due to other aspect of the lens construction but all modern LED-based reflex optics use an emitter Located somewhere offset from the center of the window. The light emitted is reflected in a collimated beam (the light is reflected in parallel so the dot stays small rather than increasing like a flashlight as the eye gets further from the lens) back to the shooter’s eye via coatings (dielectric dichroic coatings) that reflect light at certain wavelengths...so you see the dot reflected but can still see through the transparent window.

Just like looking out your rear view mirror from the offset driver’s seat in your car, in order for the beam of light from the offset emitter to align with your eye, the lens/mirror must be angled properly. In most pistol optics the emitter is centered at the bottom of the unit, so the lens is angled/canted back to align the dot with your eye. In the case of the T2/H2, the emitter is located in the bottom corner so the lens is angled back and canted toward the emitter.

Looks like my prediction is coming true. They received my optic on the 10th, and they told me the "inspection process" takes 10-12 business days. Today is day 12 so I emailed for an update. The response was "We are currently awaiting inventory to replace your RMA with, when we get some you will get a tracking number." I'm definitely gonna wind up with the HS407C-X2. Thanks Trijicon.

For putting buttons on the side of the upright and doing it differently than Trijicon? This seems like less of an outright copy and more of Holosun knowing fighting it would financially crush them and Trijicon either deciding it's not worth it or not being so sure they would win if they tried to go yard. But who really knows?

[GJM]

I received my Holosun 509T and V4 plate from C&H. The V4 plate was typical C&H quality. The overall size of the 509T was significantly smaller than an Acro. Despite that, the display appeared wider than an Acro and similar in vertical height. I find the 2 moa dot size small and prefer the larger size Acro dot. Not surprisingly, the Acro seems beefier. The side battery tray of the 509T has this tiny screw that could easily be lost while changing a battery in the field. More to follow after I shoot it, which will likely be next week.

[vandal]

Same with the 407K. They should make those screws captured, if that's possible.

Got a 509T the other day. Should have a couple 512C's coming today. Feel free to laugh at my terrible pics. On the G17, it's not mounted, I just placed the adapter in place to see what it looked like.

I decided I'm going to use the 509T on a UMP 9mm conversion I'm building, but that's been a bit of an ordeal. Not sure if anyone else has dealt with this on the 509 but, it seems the recoil lug cutouts on the RMR adapter plate are not very deep. Maybe it's only intended to be used in conjunction with a sealing plate, which would make sense. Thought I'd mention it just in case. For my UMP conversion, I bought a KDG Sidelok QD RMR mount... and same issue, the recoil lug holes don't allow a flush fit. So I have a flat sealing plate on the way which will hopefully be enough of a shim to work.

Oh man, past couple of days have been like Christmas. Got a couple Holosun HS512C's in. Along with the 509T I got the other day, I've been saving and waiting for something like 6-8 months. Been impossible to find any of these in stock.

No rounds down range yet. What I notice so far about the 512C is, it feels significantly smaller than an EOTech EXPS3, and I like that. It also feels like it has a very large window, so I'm quite happy about that.

Tightening the lock screw did feel fairly positive. I was able to tighten hand tight plus torque angle of a few degrees (just by hand) without feeling as if the screw would strip, so that's good.

Auto Mode
It's quick and easy to switch from auto to manual mode. My initial feeling on the auto brightness is that it is noticeably slow. I haven't timed it but, walking around in my poorly lit house with rooms of significantly different levels of light, there is a noticeable lag of maybe 400-700ms I would guess. Once I get done playing around with settings and get serious about configuring it for actual use, I think I'll probably leave it on manual mode.

Battery Compartment
In waiting for one of these for more than a half a year, I considered one of the 510C models. Two things held me back. I wanted a fully enclosed emitter, and I didn't want a screw-in battery compartment door. I'm not fond of some of the screw-in doors on other Holosun models. Some, like the 407/507 models, work well enough. Others, like the 403, have such small screws that they're pretty much guaranteed to strip. I like what I've seen so far with the 512C. The battery door has a spring-loaded detent that locks the release lever in place. Simply slide that detent to the right, lift up on the lever, rotate counter clockwise (I believe 1/4 turn), and the compartment pulls straight out. Seems simple and robust. I like it! I'll let you all know how durable it is in 2 or 3 years when the battery runs out. ;)

No, it's not canted. Just a weird visual effect of my crappy photo-taking skills and the angle. Same goes for the next pic.

Very interested to hear how printing is with a 509 (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx) vs an ACRO (https://www.amazon.com/Aimpoint-Acro-Reflex-Sight-Mount/dp/B07Q61DVZN/) vs 507.

[Dr. No]

Got some mileage on mine. Student used it during my red dot transition course I taught, and I ran it at team training today. The 1.1x is not noticeable in practical usage. Made hits on C zone back to 100y today pretty easily. I've decided personally I don't like the EOTech reticle, too busy and I'm used to just shooting a dot. More things to look at when I'm trying to pay attention to what the dot is doing... YMMV.

The brightness on this guy is excellent. I actually had to turn it down 3-4 from the top to have a nice crisp dot that wouldn't bloom. Most other optics I run one down from the top (RMR/Acro). So plus there.

My only real gripe at this point is that the damn adjustments are a with proprietary screwdriver-ish type tool. I didn't have the factory tool with me today and we tried a variety of things to be able to dial it up some. I ended up using the tip of my knife jammed into the adjustments. Why couldn't they have made it 2mm wider and every small flat head screwdriver on the planet would have fit it? Grumble.

Overall, really liking it.

[GJM]

I have been using my 509T (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx) a few days, and continue to be quite impressed. Assuming it is as weather resistant as an Acro, it is enough smaller in external dimensions to conceal much easier.

The small adjustment slot is common to multiple Holosun pistol optics — maybe Trijicon patented the larger slot. :o

[Steve m]

This was my first time using a MRDS for more than "range fun". I utilized my Holosun 507C V2 (https://www.amazon.com/Holosun-HS507C-V2-Multi-Reticle-Parallax-Failsafe/dp/B084VGDK6K/), on a G-19 with a CHPW plate during a LTT Advanced class Mid Sept in WV. Had no issues with the optic, I experimented with the different reticle options, ended up going with the dot. The auto adjustment mode worked great during the day, I think for daily carry I would use the manual mode. I'm no expert on the glass, it seemed clear to me, no color shading or magnification. Overall I like the Holosun optic. (I have X2 LP DPP on G17 that I have used for some IDPA nothing serious). I would and will buy more Holosun products. Now to take a specific RDS class.

[DaBigBR]

There are just enough 509Ts (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx) sneaking out there to keep me interested. I saw that Agency had some yesterday. C&H a couple weeks ago.

[MDFA]

I have 2 HolosunV2 407c RDS. I just had to return one to Brownells as the dot would not hold zero. If you tapped the sight the dot would move to the right. All mounting screws were tight and it was fitted to a CHPWS V4 Plate. The other seems fine so far.

[DpdG]

I have a 509T (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx) in hand, but the slide that it’ll go on is at CHPWS for a custom plate. Sig and their wonderful world of mounting patterns and sight configurations....

Will report further upon mounting and shooting the combo.

[GJM]

To date, I have not been overly impressed with Holosun pistol optics — ok for a price point, but not my first choice. However, the 509T (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx) so far, has changed my opinion. The display is large enough to feel good shooting, while the external footprint is concealable, the auto intensity seems good, and you get a sealed emitter. For a carry dot, if it proves reliable and the battery works to spec, this may be my favorite carry dot.

Just an update for anyone wondering about their warranty service, I'm still without a replacement for the HS407C V2 they received from me on September 5. The last update I received was that they are awaiting inventory. This may very well not be normal turnaround for them as I have a feeling that I'm caught up in the change from the V2 to the X2 and they intend to send me the X2. I don't see the HS407C-X2 (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/hs407c-x2-reflex-sights-prod137904.aspx) available anywhere for sale yet, so I suspect I won't get a warranty replacement until the first batch of those make it to the US from the factory.

[Steve m]

Just traded into my 2nd G19 MOS with Holosun 507C V2, using a CHW Precision plate, V4

[Sig_Fiend]

Finally got all the parts to finish my build. HK UMP 9mm clone using a TBT receiver. The optic mount is a Kinetic Development Group Sidelok RMR low profile mount. I used a Trijicon sealing plate as a shim as well as the RMR adapter plate that came with the 509T (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx). Without the sealing plate, the RMR mount nipples are too tall for the Holosun adapter plate, so you can't actually tighten it down all the way. I also had the same problem when I attempted to mount the 509T + adapter plate to my AIM Surplus G17 RMR cut slide, so just beware you'll probably need a sealing plate or other shim if attempting to use that adapter plate.

I have a spare 19MOS slide sitting around and am tempted to get a CHPWS plate and build up with a 509T (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx). How much does the optic overhang the slide? Am I going to have to dremmel my holsters to clear?

[DaBigBR]

Got my 509T today. The RMR adapter feels very beefy, but tightening the optic onto it causes it to flex. C&H plate is inbound and I'll move the 509T (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx) to an MOS gun.

Overall quality of the 509T (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he509t-enclosed-reflex-sight-prod134823.aspx) appears very high. Current production ones retain (as expected) the better buttons.

[stomridertx]

I checked in again yesterday on my warranty replacement for my cracked glass 407c v2. There are no 407c-x2s (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/hs407c-x2-reflex-sights-prod137904.aspx)to be had yet, but they were very gracious and offered me a $35 upgrade to the 507 which I think is more than fair. I took that option and they should be shipping out today. I guess I should give the circle dot a try since I'll have it. I've had no problems getting in touch with them and they have been responsive through email. I feel like if it wasn't 2020 where everything is stupid and insane, I would have had fast turnaround. Even though it's been almost 2 months, I'll say their customer service is good.
It's been sort of a blessing in disguise as I've now got a lot of rounds through the Ameriglo suppressor height sights, have them zeroed for my carry ammo, and know how they behave at 3, 7, 10, 15, and 25 yards very well. I put some Testor's fluorescent orange on the front sight and have carried on with them as the primary sighting system until the replacement arrives, and I'm comfortable with them now. I'm just really anxious to be able to get reps in again on acquiring the dot as I'm still in the transition phase.

[WobblyPossum]

I only ever used my 507c V1 with the Dot reticle. I recently showed it to a coworker who wanted to handle one and observed the Circle Dot reticle was canted to the left when I switched to that mode to show him. I contacted Holosun and they sent me a prepaid shipping label quickly. Tracking shows it arrived on Monday. I’m hoping my wait isn’t too long.

[Det1397]

My 407 v1 got a lot of use but finally went south with the dot not zeroing. I contacted CS via email and on 10/13 I already had a prepaid shipping label. By 10/26 I had a shipment inbound and received a BNIB 507c V2 days later! Excellent customer service from HOLOSUN.

I sent my 508T in for the same thing. The one I got back was identical. I am curious to hear if your replacement is straight. I have only used the dot reticle since.

[stomridertx]

Astigmatism can do more than make the dot distorted, it can make the circle and hashmarks appear canted as well. This happens with me, I've had holosun rifle optics with the circle dot do that only to straighten out when I'm wearing my contacts or look at it through the small aperture of the rear iron sight. If you get it back and still perceive a canted reticle, poke a tiny hole in a piece of paper and look through it at the reticle and see if it straightens out. If it does, your mark 1 eyeball is the problem and not the emitter.

Carried it elk hunting multiple days in heavy snow and -12F temps. Great compromise between display size and overall size. Not much harder to conceal than a RMR. Used it for a finishing brain shot on a bull elk.

If it's like mine, it's not only canted, but asymmetrical as well. The quadrants are different sizes. aka smunched.

Glad to hear. Thanks for the feedback.

I'm waiting for it in green -- something Holosun is way ahead of the competition on -- giving us choices.

[GJM]

I have my 509T on manual, trying to wear out the battery, and it is still going strong.

The display is wider than the Acro, and has less frame, making the display significantly more usable than the Acro for my eyes. The 509T shoots closer to the SRO, than for example, the RMR. Hope it turns out to be reliable as I really like it so far.

[JHC]

Holosun X2 series expected out soon.

https://www.thefirearmblog.com/blog/2020/11/09/x2-series-pistol-optics-holosun/

Just got my 507K-X2 (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/hs507k-x2-reflex-sight-prod137902.aspx). First pistol RDS for me. Let the journey begin.

[23JAZ]

A couple a couple clicks up and to the left in I think the 507K (https://www.amazon.com/HOLOSUN-HS507K-X2-Multi-Reticle-Sight/dp/B08G6SSTGX/) is on point. 25 yard zero completed in 25 rounds. So far so good. It is going to take some practice to get used to this but I can already see the benefits.

I received my replacement on Saturday, it was a 507c-x2 as well. The cracked glass optic I sent in was a 407c-v2, and the 407c-x2 (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/hs407c-x2-reflex-sights-prod137904.aspx) is probably unobtainium for another couple of months it seems like. I'm happy they took care of me (finally), but the inconsistency is troubling. It should be either "we're sorry, here's a 507 so you don't have to wait", or "we're sorry for the continued delay, if you don't want to wait we offer a discounted upgrade of $35 to the 507". You got the former and I got the latter, customer service should have a consistent policy here. I'm not going to bring it to their attention since I'm fortunate for them to even honor a warranty over a breakage that was an accident to begin with, as not all companies will do that.

[23JAZ]

Kenzies has Holosuns in stock. All models.

[ffhounddog]

What is the advantage of going to the Titanium version and not? I have a slide cut out for a 407/507 and trying to figure out which one to get. I was thinking a 407 or 507 in green/red and with some state police agencies running the holosun I was thinking of getting a pair for my two optic GLocks. I have a Jagerworks Glock 45 slide done for a Holosun and a Glock 19 Unity Tactical that I can change to a Holosun from the rifle optic that is on it now (T1)

[DaBigBR]

The titanium are a little lighter and arguably more durable. I'm not sure it's really that big of a deal. The 508T V2/X2 (https://www.brownells.com/optics-mounting/electronic-sights/red-dot-sights/he508t-x2-reflex-sights-prod137905.aspx) is also a little different looking if that matters.

Which state police agencies are using Holosun?

[Sig_Fiend]

Titanium is heavier than aluminum. In the case of Holosun's red dots, it means more weight. From a purely materials standpoint, I would think better exterior durability, but probably no effect on internal/electronic durability. While the titanium models are cool, for a pistol-mounted optic, the 407/507 series should serve you just fine. About the only thing you might potentially gain would be the closed emitter nature of the 509T, if that's something you need or want. In the case of the 508T or 509T vs. the 407C/507C, the titanium models are 0.22-0.50oz heavier. Versus the 407K/507K, they're 0.72-1.0oz heavier, so double the weight.

Bought a birthday present for myself. Dropped it on a Lone Wolf slide with the Holosun RMR/509 adapter. The RMR cut in the LW slide sucks and isn’t very deep. I just wanted to play around a it. It’s gonna go on a G26 slide in the near future. Fits just fine in a 6390RDS.

I just received a package from Holosun. They replaced my 507c with a 507c X2. I turned it on to check if the circle-dot reticle was oriented correctly and this one is either level or close enough that I can’t see anything wrong. I like the side loading battery tray but it does mean I’ll need to stock another type of battery. Overall, a very satisfying customer service experience.

[Tawadc95]

I found my first flaw in my 507c v2 today.
Shooting under a shoot house roof to outside target in the sun my dot disappeared. I switched to manual and the dot brightened just fine.
Later I went back to auto while in the sun and the dot worked just fine.
I went back under the shaded roof on auto and the dot disappeared.
I came to the conclusion that it was reading the light under the roof and dimmed the dot when it needed to be bright for an in the sun target.
My first thought on that is this happening to a LEO when encountering the same lighting scenario, could lead to a confusing moment when you need the dot and it's neither broken nor there.

Which is why I don’t run mine on auto on duty. The other issue is when you’re running a bright WML. On auto the WML will wash out the dot because the sight is reading ambient light and not the WML.

I like the outer ring concept but why not incorporate that with the normal dot, circle, and circle-dot options?

[Tawadc95]

I like the circle/dot combo with the Holosun for that reason. If I get off I always see half the circle.

I'm one week into having a dot and with dry fire practice I've seen a big improvement in my visual discipline on target and the dot going where it's supposed to easily.

I think I have a bit of a head start as I've always shot target focused not front sight focus so the dot is not really a big change.

I don’t trust the Holosun auto settings for EDC. They seem to work OK in bright sun, but less well in varying light, especially inside. Same for the SRO. As a result, I run the SRO and Holosun optics in manual for carry. The RMR type 2 6.5 dot seems to work well in auto.

[frozentundra]

I like the outer ring concept but why not incorporate that with the normal dot, circle, and circle-dot options?

I wonder if the extremely large outer ring could negatively effect battery life or bloom under low light in manual adjustment mode.

For close ranges, I quite like the large circle/chevron "ACSS CQB" reticle in the Holosun micro dot sight I have on a training carbine. However, I've no experience with pistol mounted optics yet. It seems like the ACSS Vulcan reticle could help address the problems of lost dots and false dots, but I'm not sure if it would cause new problems while solving others.

Images for clarification.

Which is why I don’t run mine on auto on duty. The other issue is when you’re running a bright WML. On auto the WML will wash out the dot because the sight is reading ambient light and not the WML.

What barrel and comp on the G26? Thanks.

What barrel and comp on the G26? Thanks.

Silencerco barrel and Parker Mountain Machine Comp. the comp is profiled to fit perfect with a slide that is a G5 or G26 profile. Since I was using an AIM surplus slide I had to do a little filing to make it work. I’ll touch it up some more and blacken the filed areas when I decide whether I like the comp’d 26.

Bought a birthday present for myself. Dropped it on a Lone Wolf slide with the Holosun RMR/509 adapter. The RMR cut in the LW slide sucks and isn’t very deep. I just wanted to play around a it. It’s gonna go on a G26 slide in the near future. Fits just fine in a 6390RDS.


I do not like how high the 509 sits. I wonder how much lower a C&H plate will be able to get it.

That’s one of the things I waiting to see.

I’m also looking at Jagerwerks’ direct milled option. If I decide I like it. I have a feeling that most people won’t like how high it sits on adapter plates.

What I really want is for Brownells to get on board and make a precut slide like they do for the RMR and the ACRO.

I’ve got a 507C X2 on the way. I love how low my 507K sits on my 43X and want to see what a 507C will be like on the deeper G19 cut.

Had this happen to my relatively new V2 407, haven't shot it a whole lot (350rds total), no one handed racking and carried for a bit, somewhat an annoyance as I'm coming to grips that every RDS I use does this eventually. Ironically, the reason I mounted the Holosun on my gun was because the RMR started doing the exact same thing a week ago. I've had this happen to another RMR I own, both Holosun and Trijicon have done good work on fixing this, however.

This happened earlier this year after taking two classes where a lot of one handed malfunction clearances were done off a holster.

Wow. That sucks. Have to ask, especially in the 407 that hasnt seen one handed manipulations. What is it rubbing up against? I’ve had an RMR that I’ve carried since the release of the MOS system that shown no sign of wear on the buttons.

As for one handed manipulations, since I learned to use the rear iron as the hook, my muscle memory has me rolling the gun far enough to catch the top of the optic vs the side. I’ll still need to keep an eye out. Those silicone/rubber button caps probably aren’t designed for that.

I don't understand the disclaimer: "Important Note:

Is this model somehow specific to that particular gun only? And if so...why?

That's a good question and I do not know the answer. I will say, right out of the box it went on the XL with the supplied screws. I can't imagine that you would not be able to have a slide milled for it to fit.

[DaBigBR]

I believe that the point is that every other gun with a factory Shield RMSc cut has four recoil bosses instead of two and requires milling or a plate to adapt to the 507k/407k. I know this to be the case on the Hellcat and 43X.

If you've got something else, just file or mill off the rear bosses.

[newyork]

It’s weird. I looked on Agency Arms site and they list the 507k X2 as one of 2 options for the G48/43x. They sell the 507k x2 for like $45 more than the link provided.

I wonder what’s up with that. If it’s good to go on the 48 one may as well save a little at that link except for the fact it lists it there as 365xl only.

Is Agency gtg for milling and red dot install btw?
Does the RMRc fit the 48?

I got my 507K from that guy. He wanted me to confirm I was putting it on a sig. I told him no, I'm having my slide milled for it and he replied saying he just wanted to make sure because someone bought the sight thinking it would just drop onto any ole gun. Apparently the Sig is the only model the 507K will work with without milling or a special plate.

The 407K/507K needs an adapter plate (or milling a couple of the bosses) to mount to the Glock 43X/48 MOS.

Agency is rad for milling. I have one M&P 2.0 slide milled by them for an AOS now and I’m waiting for another Glock 34 AOS slide and a mid-priced done-up frame to be ready. A bunch of our guys have Agency cuts and guns as range toys and like ‘em.

[newyork]

Excellent. I actually just bought a 2.0 compact.

I have intentionally left my 509T on manual, at a pretty high intensity, to check battery life. Been well over a month, and the battery is still going strong.

Has anyone tried this out yet?

I’m way less experienced with red dot pistols than a lot of people on here and haven’t used that sight (disclaimer)


That looks like it would work best for people who shoot incredibly slowly and have constant problems presenting the pistol. It appears to be a hardware solution to a problem that can be solved much more effectively with dryfire practice. Then you won’t have to differentiate which red light means shoot and which means you screwed up your presentation again.

I'm more interested in the chevron reticle than the giant circle. I do think the giant circle has some merit though and not just entirely for new red dot shooters.

[GearFondler]

I do think the giant circle has some merit though and not just entirely for new red dot shooters.I tried a DPP with a triangle reticle and hated it because it slowed me down... Trying to fine tune the tip of the reticle instead of just shooting when the dot was in position.
It works for rifles, not so much for up close pistol stuff... But that's just my experience which doesn't mean a whole lot.
The outer circle has genuine merit but would be better served IMHO with a dot reticle in the center.
I also imagine that chevron will look especially wonky to anyone with an astigmatism.

Honestly I've been thinking about it more for a rifle or PCC as the smaller a dot gets the more it looks like a giant starburst to me so I was kind of hoping the chevron looked actually like a chevron. I'd prefer if they put in one of their enclosed red dot optics.

[CMB]

I like the outer ring concept but why not incorporate that with the normal dot, circle, and circle-dot options?

I'd like to see other reticles INCLUDED too.

Try the 407CO. It is the first reticle I can see almost perfectly despite astigmatism. I tried many others, including the Deltapoint triangle.

[mrozowjj]

Oh I have like 4 of those already; have them on my pistols and PCCs. I love them so much.

I was hoping the chevron would be something I could put on a 556 rifle so I could actually reach out past 200 yards if I needed to. What I really want is for someone to put an ACOG sized chevron on a red dot.

The closest thing to what I mean is the Swampfox Blade but that's a prism scope instead of a red dot which is heavier and even at 1x still doesn't have the unlimited eye relief of a red dot.

I might be wrong though; I might try it and hate it. I tried a triangle RMR once but it was slower than just a dot.

Steiner came up with a cool idea too that I kind of liked:
https://www.steiner-optics.com/battle-sights/drs-1x
They have a 2 MOA dot and then under it a massive dot that is 1" at 7 yards which is like 15 MOA or something like that... basically the giant dot is for CQB and accounts for height over bore and the 2 MOA dot is for long distances.

Was thinking more for awkward/odd shooting positions, oh crap where is my dot kind of situations (error check/adjust) ...

[Rotundra]

Got mine in today. Love the concept, especially as someone who is just dipping my toes into the pistol dot pool. Instant feedback when my presentation is off.

Unfortunately, what was mentioned above is correct (for me). The chevron doesn’t play nice with my astigmatism. Not quite a comma or starburst like I get on dots, but I see multiple images of the chevron.

How does that reticle perform in dark enviornments? Does the gigantic outer ring bloom enough to be annoying when the brightness is turned near maximum manual setting? Or is it not really noticeable when the chevron is on target?

I turned it all the way up inside, and didn’t notice a bloom from the outer ring when presented all the way out.

I did notice that the chevron way more clear outdoors for me but as soon as I take it indoors, it gets all wonky. Think I’m going to return for a regular 507....

As I 1.) can't get to the range much these days and 2.) Ammo is super expensive, I determined that 2-3 range trips would be enough to buy a Holosun 507c at current fmj prices. So I bought one.

Picked it up and installed it on a Glock 34 using the provided MOS plate.

How on-target should I expect it to be just with that install? Should it be on-paper at 25 yards, or will I need to work up to that range with minor adjustments?

Nobody knows how close it will be, but this will get it very close, as in a few inches of POA at 25 yards.

^^This^^

Place an index mark at say 12 o'clock (repeatable placement in chamber), note the relative position between the laser and current iron position.

For instance, current POA / POI is centered at 15 yds, but laser is at bottom 8 ring...

Install, and torque new optic, adjust optic to old POA/POI.

Any data on battery life? I tried getting more info from holosun, but they are sticking with their "setting of 6" 50-100k hours quote depending on which version. Setting 6 is not very practical unless you only go out at night.

Also, does anyone actually check the voltage with a meter before popping in a new battery?

Got the laser that GJM recommended and sighted in. Bear in mind this is coming from a real newbie anyway, but I can definitely see the utility of the sight just in dry fire. This is obviously not news to people here, but it's interesting to me to experience for myself. Seems pretty easy to use, but holding the gun just a touch lower to look through the window instead of sights feels slightly weird.

Not GJM but here is a Gen 5 17 MOS with CHPWS plate and Ameriglo GL429 sights (https://www.primaryarms.com/ameriglo-suppressor-height-sights-glock-black). Not the best pictures, but I had these on hand. The sights sit in the very bottom portion of the window. Very unobtrusive but require a deliberate focus to acquire properly. I have a set of 10-8 Performance tall MOS sights I may swap out to see if I like them better.

509T battery life

For a while, I have thought the 509T (https://www.amazon.com/Holosun-Reticle-Additional-Batteries-Cleaning/dp/B08NWLN4CJ/) to be the best available all around carry optic for me. Sealed emitter, the flat back doesn’t accumulate debris like an ash tray, clear lens, largish display, good controls, and carries similar to an RMR size wise. My question has been battery life, ever since the Acro made me question battery endurance.

I turned a 509T on manual, a click or two down from high intensity, and have left it running since early October. Headed on a trip, I decided to pull the battery and test it this afternoon. It was the Panasonic 1632 it came with. It shows 80 percent full, so that is endurance I can easily live with, as it should last a year at the rate it is going. I replaced it with a new Duracell.

[Erick Gelhaus]

[SoCalDep]

SoCalDep - They are FINALLY doing the AOS for the M&P?

Yep... but the only plate available is for the RMR/SRO/Holosun. I tried an RMR but the irons I got were too high for my taste so I was gonna use an SRO (https://www.amazon.com/Trijicon-SRO-Sight-Adjustable-Black/dp/B07S6D2HQD/) but that ended up on another gun for an outside training class. I have a Holosun I want to install but need to get a set of Holosun-length screws. The gun looks awesome and It makes me sad I’m not shooting M&Ps as much now. I have a G34 with them that I’m really looking forward to trying out. It will have the AOS, stippled and undercut frame, with Agency trigger and magwell, and finished in two-tone OD green and black.

I have a BUIS question.

I’m going to install my HS 507c x2 on my G34 MOS with a V4 CHPWS plate soon. I currently have normal Glock sights. To guide me in selecting a set of higher sight heights to use with the optic, what is the correct sight picture to use, or does it matter?

Here’s a screen shot from a Lenny Magill video on the Holosun on a Glock for reference.

66952

Understanding this is a 2D image, is this what I’m trying to achieve with correct BUIS?

I just want steel black back ups, so should I just order the Ameriglo GL-429 set and call it a day?

66953

[GJM]

I don’t want co-witness. I want the BUIS to be as low as possible, while still (barely) usable, to maximize the display. If you are looking at the BUIS, except when your dot fails, you are looking at the wrong thing.

[Bio]

Is there a generally agreed best practice for using adaptive brightness vs set brightness of the dot? The context would be for home defense on a pistol with an attached light. Just roving around my house, I'm seeing that sometimes I'm aiming from places with one level of light into places with a different level of light, and the brightness of the dot doesn't match what is needed. I'm thinking I should keep it at a set brightness and learn to deal with that level of brightness no matter what conditions I'm in, so I'm not surprised by what I see when I'm trying to aim. Does this make sense, or are their other solutions I'm not thinking of?

[YVK]

With a WML, set brightness. The dot can was out terribly when using WML. One of reasons I don't want to upgrade my older SF lights to new 1000 lumen stuff.

[RJ]

This question is for Holosun, specifically the 507c on a Glock 34 in my case: Are there any pre-existing "Zeroing" targets suitable for a pistol mounted red dot sight? I did a quick web search and came up with several options for rifle, and one, from Holosun Canada, for HS403s, which I believe is also for rifles or carbines. The one from HS has a grid and a couple circles. (Bear with me; I'm pretty new to guns, and brand new to dots as of like Sunday.)

So my 507c has a 2MOA dot and a 32 MOA circle. I shoot fairly often at 10 yards and 25 yards. So I was pondering making a target that had a couple circles, maybe a grid, to help me at my next range session? If there's no obvious "go here and print this file" available that does that, I am probably going to whip up a *.pdf using Libreoffice draw for myself.

Can someone check my math, though? I'm using basic trig to work out the numbers.

A MOA is a "Minute of Arc" is 1/60 of a degree, correct? To generate how big circles are, at various MOA and distances, I'm using:

C = R X tangent ( MOA )

Where

C = circle size
R = range
MOA = minutes of arc, expressed as degrees/radians

(all this with correct units of course)

Using that in a spreadsheet (cause I'm lazy) I get numbers like this:

At 10 yards:

2 MOA = 0.209"
32 MOA = 3.351"

At 25 yards:

2 MOA = 0.524"
32 MOA = 8.378"

If someone can verify the math, that'd be great if something like this ends up being useful.

At 25 yards:

2 MOA = 0.524"
32 MOA = 8.378"

If someone can verify the math, that'd be great if something like this ends up being useful.

Slytac training and kinetic consulting both have pistol rds zero targets online

Thanks, the Slytac target for pistol RDS sights has 1" squares and a center aiming dot:

I could not find the Kinetic Consulting target not behind a log-in wall. Scratch that, I did see a result with a pdf file with a 1" poa and a 1/4" grid:

https://inntakt.de/wp-content/uploads/2020/01/Rifle-10yd-Target-one-third-mount.pdf

Neither of those has a grid sized in MOA increments, and don't have aiming points corresponding to the dots. I think a combination of the use of a laser boresighter (as GJM has suggested) to get close, then a simple aiming point at the range to dial in the sight probably should work for my purposes. I will most likely go ahead and design a target specific to the HS 507c since 1) it's what I have and 2) I like designing targets.

I appreciate I may be overthinking this, but I find this kind of stuff interesting.

Great ideas, thanks. I went ahead and made up a couple for my use, and posted them in the printable targets thread. My obliged.

I have a BUIS question.

I’m going to install my HS 507c x2 on my G34 MOS with a V4 CHPWS plate soon. I currently have normal Glock sights. To guide me in selecting a set of higher sight heights to use with the optic, what is the correct sight picture to use, or does it matter?

Here’s a screen shot from a Lenny Magill video on the Holosun on a Glock for reference.

Understanding this is a 2D image, is this what I’m trying to achieve with correct BUIS?

I just want steel black back ups, so should I just order the Ameriglo GL-429 set and call it a day?

GL429s will be usable nubs similar to what GJM says you want. The Dawson MOS RMR cowitness sights will give you a lower 1/3ish sight picture.

I got a 508T in. Really dig it, seems like a professional version of a 507. (508 is in the middle)

Those 508T's look good. I think my next MRDS will be a 509. I've put off the ACRO due to the battery life.

FWIW I use the Kinetic Consulting target to zero all my pistol optics. That 10 yard zero hasn't required more than a click or two at 25 yet.

What are the effective differences between the 508t and 507? I have a 507C and a 507t green dot, which is probably my all time favorite. But I'm always open to the latest and greatest. What makes it the professional model?

Probably the biggest difference is it's titanium construction that reportedly makes it more durable. You can also notice in GJM's picture the windows are a little different in shape. My honest favorite feature of the 508t is that all of the Holosun logos are more subdued. Holosun proudly and loudly advertises their logos on the 507, etc. Reticles, color, etc. is all the same as the 507 as far as I'm aware. I have personally shot and played with the 508 and although I like it the differences didn't out weight the cost of replacing my three 507's.

I used the 508t on my 92 for a few months and went back to the 507. The flat top, and thus smaller window, made the dot reflect off the top in some lighting/dot brightness scenarios and bugged me. Didn’t feel I really needed the titanium body and $130ish higher price tag. I did like the blacked out logo. Nothing a sharpie didn’t fix on my 507 though. I also feel like the rounded top prints less with certain shirts as it’s rounded rather than pointy like the 508 or RMR.
