1911/2011 adapter plates

[Tokarev]

Just wanting to put a quick RFI out for adapter plate options for the 2011/1911 pattern.

The Dawson DPO would seem to be a great option. I think it looks good on the pistol and there are a good number of optics plates. Down side is it doesn't seem to be available from too many shops. Vulcan doesn't do it nor do a couple other fairly well known 2011 shops. In fact the only place offering it (other than Staccato for their guns only) is dscgunworks.com

Another option is a cut from CHPWS although I find the options confusing. Are they offering the Staccato cut is are they using something proprietary?

And then the old standby is the Trijicon RMR plate with the built-in rear sight. Of course this only works with RMR footprint unless another spacer/adapter is used.

A final option is a plate from Dynamic Weapon Solutions. It looks like it fits the RMR adapter cut but allows for a 509T to be directly added. I assume other options would be in the works. https://dynamicweaponsolutions.com/collections/accessories/products/2011-1911-mounting-plate

Anything else out there?

Of course the best option would be some sort of direct mill solution. But I would like to retain an ability to use other optics as technology and personal preference evolved.

Thanks.

Chambers Custom plate?

Chambers Custom plate?

[Eyesquared]

Atlas sells slides cut for their plate although I don't know of anyone offering milling for that plate as service for existing guns (edit: looks like DSC Gunworks does). AccuracyX (more known in the bullseye world) will take an existing frame and install a slide with their plate system, barrel, slide stop, bushing etc.

Then there is Wilson and Nighthawk which both have plate systems although I think Wilson is not working on non-Wilson guns right now. It sounds like Nighthawk is though.

Looks like a pretty decent option. Does anyone know if he has other optic options in the works? At present it looks like RMR, Holosun K and 509T.

I am totally in love with the Nighthawk IOS.

It returns to zero, it mounts super-low, you can get custom stuff made, it’s easy to change at a user level, you can go irons only with elegance and ease, and the machining quality is superb.

We are blessed to have so many options.

Anyone reputable doing these specifically for the Acro or MPS or 509T footprints?

[rayrevolver]

A guy on Addicts said this guy did an optic cut:

"Santurri is a gun smith that is a 2011 residential expert in my area."

It looks like it's DUO/DPO compatible.

https://www.santurriltd.com/

I found another link on Addicts saying these guys also provide optic cuts, possibly DUO/DPO:

The depth of a cut you can put on a 1911 slide makes me wish there was an optic rail standard for pistols, because a rail milled deeply into a 1911 slide, that didn’t force someone to give up too many options for optics would be the tits.

Yeah man, but for me with a single high $$$ 2011, it makes sense for the plate at this point in time.

If I had a "Plain Jane" $2000 Stac P I would consider the direct mill... and still probably get a DPO/DUO cut.

In the Glock world I would mill for the Acro system (even though the EPS looks like a good setup and there are more options with that RMSc pattern). The ATEI with shim looks decent too.

DSC and CHPWS are my only options for the DPO. Staccato will not work on older STIs.

Yeah, I’m going with a plate right now too (Chambers whenever I decide what optic I want), but I wish I didn’t have too.

In a brief telephone conversation with Ian, CHPWS uses a unique cut for 1911 slides that is not the DPO. Maybe I misunderstood him. Or maybe that's his way of saying they're using Dawson Precision intellectual property without breaking to it.

One thing CHPWS will do is make a custom plate for those 1911/2011 owners running the Trijicon CA428 RMR adapter plate.

An adapter plate based on the Trijicon plate makes sense. The cut has been around awhile so there should be a decent amount of 1911s and 2011s already cut.

The new CHPWS plates don't have the tabs on the lower forward leading edge, I wonder if that is to skirt the IP issues you mention? I have an older CHPWS Acro plate that has the tabs, and also a 10-8 style rear sight.

I am ready to send off my 2011 and just get the damn thing milled. Going to call DSC on Monday and maybe even CHPWS, although I am nervous with how many horror stories seem to keep popping up. I wish Vulcan did the DUO/DPO, they *seem* to me like they can be trusted, and I would have sent it off.

[CSW]

My Springfield slide is on the way back from CHPWS, after getting a direct mill for a RMRcc. I'll post it up when it returns.

[rdtompki]

I didn't need an iron sight co-witness option to the Suarez adapter plate as installed by Mod 1 on our full-size and commander 1911s seems to be a good option. Very fast turnaround and a good price. Pictures attached are of a Kimber HD Pro Carry that I'll use for nightstand and occasional open steel challenge classes (not that it's an open gun). I suspect the adapter is thicker than the comparable CHPWS just based on the installation on my Staccato C2, but still low enough to have little, if any, effect on my presentation versus iron sights. Holosun 507/ACSS has been mounted. Not as sleek as a 507K would be but fine for our applications (My wife's full-size 1911 with this same installation is also for nightstand duty). FWIW how much would it have cost Kimber to add forward serrations on the slide? Should have had it done when are two copies were converted from 38S to 9mm.9333693337

They didn't pick up. I have the paperwork filled out with DSC and am going to wait and see if CHPWS has a sale coming up.

If I can't find an Acro P2, there is no reason to rush into a mill job, unless I go with CHPWS so they can include a plate for my Holosun.

DSC said they would modify my older CHPWS Acro plate that has the tabs but not the extra mounting holes for $30.

You ready to send off that BUL? What are you going to do?

I heard from an internet rando that Aimpoint would have Acro P2s in mid-October. So I have some time to get my crap together. I am probably going to offload an HK USP 40 fullsize so I will have cash to make it all happen at once.

The front runner is DSC for the DPO cut. I talked to ATEI a while back, they could do a direct mill Acro and install the shim sight. BUT again this is limiting to the Acro footprint.

Chambers doesn't support the Acro yet. Nighthawk IOS is probably the best solution, but expensive, and no Acro yet.

With news of a Springfield 2011 hitting the market, I am curious. If it takes STI mags, it could be a player and I can leave my Costa Comp unmolested.

It is being "leaked" over on 1911addicts that this gun does accept STI-format mags. I can't imagine SA going another route unless it was Para format. Even then, that would probably be a mistake.

At this point I'm more curious about the optics footprint. Will SA do a direct mill for the RMR or LDP? What are they doing now for the XDs and stuff? Do they have their own version of the Glock MOS that can be applied to a 1911 slide?

I did not know that this plate existed, so thank you! I sent an email to DWS to confirm that the plate will fit a 1911/2011 slide that has already been milled for a Trijicon RMR 1911/2011 plate, and they replied quickly to confirm. I currently have three STI/Staccatos all with Trijicon plates with RMRs mounted (all three milled by Vulcan) and would love to mount a 509T on one or two of them as it is my current favorite optic! Probably going to pick up one of these plates ASAP.

Will do. Just placed the order. Now to decide which gun to put it on...

[rayrevolver]

Just talked to Dave from DSC.

I am going to have him:
- Mill for DPO, cerakote only area cut - $200
- Drill 2 holes/chamfer in my older CHPWS plate - $30
- Install Front Sight, Laser Boresight $45 + $25 or $35

Shipping/insurance - $30

It's time to nut up or shut up! Been wanted to do this forever. He said he has an Acro P2 he can mount for pics of the sight picture. I am going to request the lowest possible front sight, even if it means a 6 o'clock hold if I need irons.

Unfortunately I have only received an order confirmation email. My guess is that they only make these when ordered, so it is probably in the queue for milling and then will get sent out for a DLC or Black Oxide finish. If I dont hear anything from them within another week or two, I'll reach out to them for an order status update.

DSC got my slide/barrel on Friday, 2 Sep. I assumed it would be 2 weeks before I heard anything. Wed, 7 Sep, I got these pics.

He installed a 0.215 front sight.

Another note, this was the older (and I purchased used, the previous owner used a green locktite) CHPWS Acro plate. It has the tabs at the front leading edge, the "10-8" rear sight, and did not have the 2 holes for additional mounting. DSC mounted his Acro for these glamour shots. I never got the single bolt at the back of the CHPWS plate. So if you have one laying around or know where I can buy one please send me the info.

...now all I need is an Acro P2...

From what I understand, its just another plate option from Cabot. I liked what I saw but the only option right now is an RMR plate but I could be mistaken.

Got the slide back yesterday and I am happy with how it turned out. I found the "big" bolt for the rear DPO/DUO plate on Ebay, so I have 10 of those incoming. Sound off if you want one as a spare and I can ship out.

Did he cerakote under the cut or leave that section in the white?

I should get off the pot and send him my BUL slide. It would be a straightforward job, I assume. Only additional thing that may be required would be flat topping the BUL slide to match the flat profile on the Staccato iron sight plate. But then if I run an optic on there it probably won't even be anything someone would notice.

I can only see a small ledge at the rear but it looks to be black. For now, I will assume he did the entire area.

Waiting for an Acro may drive me crazy. I can buy an EPS with a plate from CHPWS for $433 (25% off the plate with EPS purchase). We'll see if I can wait for Aimpoint to get more in stock or roll the dice on the EPS.

Have you reached out to Vulcan about doing the AOS cut on your BUL?

Some thoughts on DPO/DUO with respect to the 407k/RMSc mounts.

It looks like they use the same bolt configuration as the DPP.

Can you direct mount an EPS or EPS Carry to a DPO/DUO?

I did notice that the Dawson plate shows a bolt with a shank that goes through the optic, then plate, then into the slide. Do these plates have the center bolt in the back? It doesn't look like they do.

https://v1tactical.com/wp-content/uploads/2021/04/401-005.jpeg

The CHPWS plate uses those Tnuts for optic to plate... Which means there is only the single bolt to attach it to the slide? The HW in the pic says it has bolts to attach the plate...

Everything showed up yesterday, 509T X2, CHPWS plate, and E6000. I won't get to the range until later next week, so plenty of time for the E6000 to cure. I figured I would try E6000, don't want to eat this optic...

The 509T CHPWS plate has a higher machined ledge for the center DPO bolt and it was not a torx like their website says. Its a better setup than the Acro, which needs to go over top of this bolt. Its pretty beefy and I can easily check my torque striping during a shooting session.

At this stage I am going to pass on the Acro P2 and just shoot this setup, as much as I wanted to go that with Aimpoint. I am curious where my irons will print with a .215 front vice a 0.195 that 10-8 recommended.

The co-witness is very low, 1/4 or 1/5, and very unobtrusive. The 509T took about 10 clicks right to drop on the front sight, no elevation clicks.

Not picking on you rayrevolver because I know you were wanting a P-2. But I always kind of chuckle when I see pictures of someone's Staccato, Atlas, ZEV, etc decked out with an O-Light WML, Holosun 407, etc.

Looks good. The DPO cuts appears seemless with the pistol.

I picked up a Prodigy 1911 DS 4.25" recently, so I'll just pick up a 509T plate for that when they become available. I have a Burris Fastfire 4 installed on the gun temporarily using the included Hex Dragonfly mounting plate (same footprint) until they release the various plates for the Prodigy.

Me too.

I was kind of wondering about picking up the Primary Arms Docter footprint but there are reports that it doesn't fit the Agency plate. Screws aren't right.

Other options include a fairly new optic from Crimson Trace called the RAD. Available in green or red and with or without the motion sensor. If I can find one for $200-ish I might give it a go just to stick something on top of the gun.

That is about where it ends. The optic would turn itself off after about two minutes and would not turn back on after any amount of shaking or jiggling.

The optic is already in the mail on its way back for a refund.

I already had to send my Fastfire 4 in for warranty replacement due to the dot moving to a new place in the window with each shot fired. I'll be really happy when Springfield starts shipping the pre-ordered plates! I've got a Holosun 508T ready to go on the RMR footprint plate that I ordered.

I got the charges reversed via my credit card company. Then, a month and a half after I placed the order, DWS emails me to ask which optic I wanted the plater for. 🤦

rayrevolver got any updates on this? How's the DPO cut working out?

Been working too much, only 200 rounds on the 509T X2/CHPWS combo. It has been great though and I am very happy with the optic so far, enough that I passed on an Acro P2 again. Still haven't seen an Acro in real life to know if I am missing anything.

Glad I did the DPO cut, having flexibility will be nice down the road. Hopefully get shooting next weekend. Have a new case of 124gr ammo I want to try out.

Any long term updates for us?

Any long term updates for us?

Because I can't leave well enough alone, I did finally upgrade the 509T to a P2. I installed the CHPWS plate with the E6000 glue and no issues in 1000 rounds, installed Dec 2022.

I am using the original/Gen 1 CHWPS Acro plate with a skinny fixed rear sight. I like these CHPWS plates because the rear bolt is substantial and I can easily check the witness mark. I have no idea if the 2 smaller bolts are loose without removing the optic. Based on holding zero I assume that things are holding ok.

Looking at my logs, I last shot in June. Went on vacation in July and then kids sports started up. I need to get back to the range.

This STI is a lot of fun to shoot. I installed that fatter grip and arched MSH. Its great now and the only pistol I want to shoot. I'll bring the G5G26 along next time.

EDIT: I forgot I posted pics of the old school CHPWS plate.

So I went and looked at the current CHPWS Steel Acro plates and they removed the large bolt at the rear. I wonder why??? I would rather have 3 fasteners than 2, and I can see the head on this one with the optic installed. Weird. Based on these changes, I won't upgrade my aluminum plate unless I need to.

Can you refresh my memory? DSC did the optic cut on your slide?

I find myself curious about aftermarket cuts again with the purchase of an EAA Witness 2311. The slide is cut for the Holosun K footprint and there is no rear sight on the slide. Not that I necessarily need one but it is something I would like to have.

The leaves me a few options. Have the slide cut for the DPO. This with an appropriate plate is $350 or so. Another option is the CHPWS cross plate. This with appropriate plate is $285 or thereabouts. Another option is have a small dovetail cut in front of the optic and go that route. This is the least expensive but then the gun probably won't fit in my USDG holster. Lastly is just run the EPS Carry and get a super low height front sight to get POA/POI with the built-in rear. Or keep my existing front sight and figure out what kind of sight picture I need to get acceptable hits at 10 or 15 yards. I'm assuming I can make a triangle with the front sight and make it work.

Yup DSC did the DPO cut. Can you do the DPO cut on the 2311 that is already cut for a Holosun K?

I haven't been to Vulcans website in a while, but are they making cuts with rear sights? What about that company that did the shim sight for a rear, ATEI?

Monsoon says he can do a forward dovetail but a Glock sight will overhang the sides of the slide a bit. Cosmetically maybe less than ideal but functionally probably fine.

I wanted to give an update on this... even after the charges got reversed on my credit card, and I told DWS that I reversed the charges, they STILL sent me a plate. Of course, I was so disgusted with the whole experience that I just stored it away and forgot about it. I recently sent my older STI's upper off to have barrel ports done by Impact Machine (the slide previously had the top window cut done when it was milled for the Trijicon mounting plate), and I decided I would finally install the DWS plate with a new 509T when I got the upper back. Unfortunately the DWS plate did not fit the Trijicon plate cut... at all... so I had to custom fit the plate to my slide and then refinish it in Graphite Black Cerakote. I would've been furious if I had actually paid $200 for this plate and waited as long as I did only to find out that it didn't fit, but since it was essentially free and I can fit and refinish this type of thing myself, I am very happy with the gun now that it has barrel ports and a 509T installed on it.

That actually looks good. Too bad the company seems super sketchy.

Dual Hammer is another source for the Dawson optic plate cut.

From what I’ve seen from them they do a good job. I want a Nighthawk IOS on my MC Operator but the price point of a Dual Hammer job is really tempting.

AB Prototype is offering the Atlas Gunworks plate cut

I’m considering milling one of my 1911s for a RDO instead of spending money on a new pistol. It would probably be my Ruger LW 5”, and would be for either a RMR or less likely an ACRO.

I see AB Prototype is offering the SA Prodigy cut which would be versatile:

Both the RMR and ACRO are listed as being iron sight usable per SA:

It’s that simple?
