First Shots: Glock 26 with KKM barrel and Comp

[Tensaw]

I looked around the net fairly extensively trying to find some information on a Baby Roland, but I did not meet with much success. So I bit the bullet as it were and plunked down my $300 for the KKM barrel, comp, and thread protector, and then waited. This is a look at this rig that I hope will helps others who are considering going down this road.

First some specs. The pistol is a Gen 4 Glock 26 that is outfitted with an Apex Extractor, White Sound Defense HRED, and a Gen 3 trigger bar (and the correct ejector). I am running a variety of mags including the factory 10 rounder with a factory plus two extension, the MagPul 12 rounder, and a G19 with the Pachmayer grip adapter thing. This pistol continues to exhibit weak ejection. The combination of the Apex extractor and HRED has yielded more reliable ejection and minimized the BTF with the factory barrel, but the extraction is still weaker and more erratic than I would like. That said, it is also clear that hotter ammo causes more vigorous, positive extraction and ejection. Okay, enough of that bunny trail.

The new barrel is the standard KKM with the (I believe) 9/16 threads and their comp. I ordered the parts from KKM on 9/9/17 and they shipped on 9/26/17. This was well inside the four week lead time indicated on the website. The parts arrived well packaged and in good shape. No instructions enclosed because if you need those for this, you would probably be better off with a sharp stick.

The machining was excellent as you would expect from KKM. Everything that needed to be polished, was – and no crud in the lands and grooves. It looked ready to go right out of the box. So, as I go to install the barrel for the first time, I have this micro-second of panic. The barrel did not want to just drop into place. Whaaaa?!?!?! Am I really going to have to get this thing fitted?!? Nope. It was just a very precise fit. Just a little bit of jiggling and it fell (actually almost “clicked”) into place. Yee haw! Very clean threads at the muzzle, but they are also very fine. Careful with the first turn, and then the comp glides on from there. It snugs up just right to the front of the slide with maybe an 1/8” or less gap. Once the recoil spring is put in place, the face of the recoil spring assembly that protrudes just slightly through the front of the slide will actually obstruct the comp if you try to unscrew it off the barrel with the recoil spring in place. So, how ever much the RSA protrudes through the front of the slide, the comp fits closer than that.

I had thought that the comp might look goofy with the rounded nose of the G26 slide, but I don’t think it looks bad at all. That was not going to be a show stopper for me in any event. As it is, it looks like a friggin' ray gun.

With everything installed and just working some drawstrokes, the comp is, visually and in terms of balance, a non-factor. From the shooter’s visual perspective, the comp disappears. And even with an unloaded mag, the gun is not muzzle heavy at all. The one thing I did notice was that reholstering was a little more touchy with the comp in place. The width of the comp is fully the same as the width of the slide. I am running an RCS Eidolon with the high sides. This holster is very precisely fitted to the pistol so I have to slow it way down and be a little more precise to get the comp started in the holster. From there, its no problem. This gets me to the overall length of this rig.
With the comp installed, the OAL of the G26 is very slightly longer than a G17. Yup. To my eye, the comped G26 stops right about where the end of the barrel on the G17 ends. Wild stuff. Before ordering, I was trying to visualize what kind of length this was going to add to the 26. I *thought* I would end up with a G19+ OAL – so somewhere between the 19 and 17. Nope. I have only run this in the Eidolon (which has the open muzzle) and an Alabama Holster pancake for a G17. The Alabama Holster has the muzzle end sort of rounded in whereby it creates a bit of a stop for the slide, but it is not so closed that the kydex would touch the barrel. In any event, the pistol fit fine in the Alabama Holster pancake.

Now for the main part of this review. Does it, or don’t it, work? It do. I started with relatively weak ammo and worked my way up. First shot was with 115 grain PMC. This resulted in a stove pipe with the brass sticking straight up at 12 o’ clock. No big surprise really. I ditched that and went to some Perfecta 115’s. Surprisingly, that ran just fine. Not only that, but it was super soft and flat shooting with the comp. Let me say right here that, despite my best efforts, I have never been able to track the front sight in recoil. At best, the sequence is: front sight – bang – blur- front sight. The comp did not change this. What it *did* change is the time between front sights. With the comp in place, the front sight is disrupted very briefly, then it reappears in the same spot from a moment before. The comp absolutely makes the gun recoil flatter. Muzzle flip is almost eliminated. This was true across all ammo I shot. Other ammo included some Winchester NATO spec 124 grainers (this stuff is hot and flashy) and a variety of HST with some of that being +P. Again, the effect of the comp was evident across the board. My buddy had his G26 with him and we shot them back-to-back a few times with the same ammo. The comped version is like a different gun. While we did not shoot the comped 26 against a 17, I think the comped 26 would probably recover quicker than a stock 17. That’s just the sense that I get.

We were able to shoot on into dusk. Some flash through the ports was evident as the light dimmed. Honestly, the flash through the top ports was fairly distracting. I ran 10 rounds of both the 115 German MEN ammo and the Winchester NATO (one mag each) as fast as I could run the trigger at about seven steps. After the first shot, I kind of lost visual on the target. Nonetheless, I kept on keeping on and about 8 of the first 10 rounds were A zone hits. I attribute that to the recoil mitigation of the comp. The second 10 round dump was with the NATO stuff. Very flashy and more recoil (perhaps the most of anything I shot) and the A zone percentage probably dropped to 50% - but again, I was mashing on the trigger as fast as I could and I really could not see the target after the first shot due to muzzle flash. All the hits were, however, on paper and I think everything was in at least the B zone – for whatever all that is worth. I did not shoot any HST as it started to get dark (I should have done that), so I can’t comment on how that ammo would perform. One last thought on muzzle flash. Particularly in the short barrel of the G26, I wonder if the comp makes the flash only a little worse by directing some of that up around the front sight. For sure, this is the worst direction we could send the muzzle flash, but I wonder if it is that much worse than it would be with a stock set-up. I mean, a given ammo is gonna flash at whatever rate, so you will be dealing with it regardless. I will try to remember to do a side-by-side comparison at my next opportunity.

Also, the ejection perhaps improved with the KKM barrel in place. With the factory barrel and Apex/HRED/factory EDP in place, I was getting better ejection generally, but still about one piece of brass per mag coming back toward my noggin. Neither I, nor my had this happen with the KKM in place. With the weaker ammo though, the brass came out like from a popcorn machine – no pattern. With the hotter ammo, we saw positive ejection to 3 – 4 o’ clock. I am going to try some 147 grain +P HST. My theory is that this will give the comp plenty of gas and also help with ejection.

Overall, I am *very* pleased with the KKM set-up. It does what it is advertised to do – it makes the gun shoot flatter. I am glad I did not go full-Roland on this and comp my G19. That would be a little more than *I* would be inclined to carry. That extra muzzle length does impinge on my comfort when carrying AIWB and the G17 length is about my limit (other folks may have more room than I do down in the nether regions :p). So for me, this is a great set-up. This is my go-to carry rig.

What would I change with this set-up? Two things. I would love to see KKM come out with a version of the comp that would facilitate mounting the front sight on the comp itself. I have to think this would aid in tracking the front sight. There would be some challenges with this – mostly that the sight would get sooted up pretty quick; but I still think it is an idea worth pursuing. The other thing is the grip shape on the Gen 4 G26. Why Gaston went with the curve at the top of the back strap I will never know. The Gen4 G19 grip shape just sinks into my hand. With the G26, I feel like I have a gap between the gun and my hand near the top of the grip. And there is no good way to fill this in. I have absolutely considered cutting up a perfectly good G19 both on the muzzle end and the grip to get what I want. But I’m not there – yet. In any event, I’m sticking with the 26 because it allows me to scale the concealability up or down depending on what I have going on. The next iteration for this project will be to install an RMR. That said, I am going to wait for the Gen5 26 to hit and see how that goes. If those run like the 19s, I will probably grab one up and RMR it. Here’s hoping that the KKM barrel will work with the Gen 5.

ETA: I wish KKM would have tossed in a couple spare allen screws. I know I will end up losing the ones that came with the comp.

Wait. You typed all that up and didn't include pics? Epic fail, bro. I kept scrolling down waiting to see pics of this magical blaster on my phone. But nothing.

You failed the internet today. :mad:

[Poconnor]

Pics or it never happened

[JHC]

Myself and another more experienced shooter have observed more consistent ejection patterns in our Glocks with KKM barrels. I've never seen the exact mechanism of that explained. Of course it may not be real. I think it is.

[Bigghoss]

TL;DR I'll come back when I'm on a computer and not on my phone. And when I have a few hours to kill.

Seriously, though. Good post. The Roland/mini-Roland concept has intrigued me. I've been toying around with building a G26K Roland Special.

Edit: I meant to post this right after my first post but forgot to hit the submit button. So it sat there in forum purgatory until I came back to the forum.

Nice video. Pretty flat shooting. So now we need to get someone with a slow mo camera and a grid wall in the background to shoot this and an on comped 26 side by side so we can compare the recoil between the 2. Who volunteers?

[Balisong]

Very interesting project, thanks for sharing. I'd love to see a follow up with side by side comparisons with a G19 and G17 in terms of flash and split times. For that matter the same comparisons against your friend's stock G26 would be really cool.

[Tensaw]

Yeah, so my take-away on this concept is, if you are on the fence - do it.

Also, the linked video plays on the fancy iPad, but not on my jalopy of a laptop running Windows 7.

[Tensaw]

Lon & Bali - So YouTube has a few comparisons (one even slo mo I think) of 19's comp vs. non-comped (no baby Glocks that I found) that I watched before taking the dive. Honestly, those vids kind of made me question the effectiveness of the comp. But behind the gun, there is no doubt it works. I was very relieved that this worked as well as it does.

It could be that the shorter barrel of the 26 let's the comp do more work than on the 19. And taking that a step further, cause that's what I do, I really wonder how this would work for baby G's in 357SIG and .40.

[Balisong]

Yes I was also wondering if the comp made a bigger difference on the subcompacts vs compact glocks, and as I carry a G27 I'm also quite curious about how it would perform on one of those. I've got a Sig 229 Sport in .40 which is stainless and comped, but I never had a stainless non comped 229 to compare it to, only the aluminum framed models.

[Dismas316]

Now that's what makes a good post, pics and video. :D My question to you is outside of the comp, did you shoot much with just the KKM barrel? If so what are your overall impression of just the barrel vs. the stock glock barrel? By the way in the video that gun hardly moved so you can certainly see the comp reducing the recoil significantly .

[Tensaw]

Yup. What I wanted to do was go G27 with KKM conversion barrels in 9mm and 357 SIG, along with a .40 threaded barrel, all threaded for a .40 comp. That would truly be a do-all rig, but you would also be well past a grand deep on that - without an RMR. Too, I think KKM changes the thread pitch on the .40 compared to 9mm. (Their website is kinda sucky.) They could probably do a one-off on the threading, but now we are talking mo' money and lead time. So I "settled" since I already had a G26 which was mostly collecting dust. I'll just have to be content slinging 147 grainers down range at +P speed.

[Tensaw]

Dismas - No, I did not compare the KKM barrel with and without comp. What sort of comparison are you thinking about?

I did no accuracy testing of any kind other than shooting 6" hanging steel at 25 yards or so with four or five rounds. No problem there. As noted, the lock up on the KKM barrel is significantly better than the factory barrel. Also, aside from the very first round of weak 115 PMC which stovepiped, no malfs of any sort occurred. We probably put 100+ rounds down range using various mags - not exactly a torture test, but a decent start.

One pic I did not take was to compare the OAL of the threaded KKM barrel with a stock G19. I strongly suspect they are very close in length so we should be getting muzzle velocities on par with a 19. Yet another little win.

Right or wrong I threw a little red loctite on the muzzle threads and blue loctite on the sets screws. Anybody got a take on this? Not needed?

Actually, I find THIS particular combo to be quite interesting.

[Dismas316]

Dismas - No, I did not compare the KKM barrel with and without comp. What sort of comparison are you thinking about?

Some have felt the the KKM barrel improves accuracy and was just curious if you were able to tell any difference. I had thought about the barrel in my 26 in the past and was curious as to any differences. I doubt I would go that route, I'm pretty accurate with my 26 and doubt there would be significant difference. Was just wondering.

The comp has me intrigued, especially with my 357/.40 combo. I like you idea on the g27.

[Lon]

Actually, I find THIS particular combo to be quite interesting.

I did too. Will it work?

[Tensaw]

If I am reading the horrible Glock Parts spreadsheet correctly, Glock lists two different part numbers for the locking blocks on the Gen 4 19 and 26. I will crack those open at some point and see if my eyeball can locate the difference. Wondering if it won't be rail length. Mine did hand cycle just fine - dry, no ammo.

[Hambo]

What, no RMR on that?

Just kidding...I like the way you think. You could try some 9BPLE in that thing. ;):D

[Bigghoss]

Ok well I don't have the time to read the original post in it's entirety I did stop by for the pics. Looks cool and I'm intrigued.

[Tensaw]

Well, throwing the G26 top end on a G19 slide is a no go. The front slide rails on the 19 frame are about 3/8" further forward than on the 26. This limits the rearward travel of the G26 slide to the extent that it will not be able to strip the round out of the mag. Dang it.

Now I'm tempted to take one of the G23 frames I have and see if I can trim the rails back to work with a 26 slide...

I have two sitting around, a G22 lower wearing a .22 lr slide, and one with a 9mm upper chopped to take G19 mags. I think at some point one of the G23's is getting made into a Roland special but that will be a while.

A G26 slide with a comp and RDS on a modded 19 frame running a TLR1 or APL could be some hot stuff.

[rayrevolver]

Very interesting. I absolutely loved shooting and carrying a G26 but moved to a no carry state. Its been sitting for close to 7 years.

I am going to see about getting some HST low light shots on video this weekend. That said, does anyone have a recommendation on which HST to go with for a carry load? Bullet weight and +P, or not. I had initially thought the 147 +P would let me get the most out of the comp, but the comp seems to work with even cheap 115 grainers. Looking for a load that will feed reliably while giving good terminal performance without generating unnecessary recoil. Kinda thinking 124 +P, but what do I know?

[MSparks909]

Try the 124+P HST's. That's been my go-to carry load for about a year now. Previously it was Speer Gold Dot 124+Ps. The extra "oomph" from the +P loading should be mitigated by the comp. As a general rule with pistol comps, it's usually more preferable to run a lighter bullet with more powder as opposed to a heavier bullet with less powder. The more gas/powder used, the more effective the compensator is.

[Bigghoss]

With regards to modding a G19 frame to work with a G26 slide, it's not gonna work. I pulled out a G23 frame and my G26, both gen 3's. The front slide rails on the G26 are farther back and trimming the rails on the 19/23 frame would leave almost nothing left of them. It looks like if someone had the resources they could make a G19 frame with a G26 locking block and rails. Seems like that would require some connections to someone at either the Glock factory or at an aftermarket frame maker. I doubt a polymer 80 frame would work as I would think it's setup to be used with G19 parts but without one to look at I don't really know.

[Tensaw]

Yesterday evening I went out and shot the KKM comped 26 alongside a stock 19 and a G35 with a KKM 9mm conversion barrel (yeah, KKM is getting way too much of my money). Everything captured on video was some iteration of Federal HST. I cannot say with any certainty what weight bullets these were (probably 124s and some 147s, but I really don't know). I don't think there was any +P in the mix, but I can't say for certain. The point of this exercise was to get some muzzle flash footage for you people. If I can ever get my iPhone footage to upload, you will see the same shots from both the shooter perspective (head worn Go Pro) and from the side (iPhone).

During the course of shooting, a couple of items of interest appeared. First, the KKM'd 26 was printing at least 6" high at 15 yards. I had to hold at the bottom of an 8" plate to get hits within a couple inches of the top. I was pretty shocked by this because I failed to notice this the first time I took this rig for a spin, but I think I was shooting at about 10 yards or closer that time. But it was pretty consistent - at least with the HSTs, but I think all the loads I shot were about the same. For reference, my sights are Ameriglo GL-301 (iDot Pro). I can't find specs online, but I believe the front sight is going to come in around .218 or .220 in height. If anyone has the factory spec on these, please advise. I am looking hard at the Dawson Precision offerings, but I have to get back out and get some rounds on paper and see what I'm really working with here. I will post up those findings if anyone cares. Anyway, the G35 shoots dead on and the G19 is somewhere in between. This was not helping me get hits as I swapped from one to the other, but that wasn't point of the exercise. I will say that once I figured out the hold on the 26, as long as I did my part, the hits came.

Regarding muzzle flash, I will say that it simply was not a problem with any of the pistols. For sure, the KKM throw some flash north, but the pistol settles back down so quick and flat, it was a non-factor as far as reacquiring a sight picture. Also, on the footage where it is noticeably darker outside, you will see the brightness come up - that (the brighter look) is a more accurate representation of the lighting conditions. It was dusk, working toward dark, on those. And the flash you see through the lens is close to my observation. If anything, the flash is over-represented on film.

The comp does its job fine with the HST loads. You might be able to detect the diminished muzzle flip on film, but it was very detectable behind the gun. The comped 26 settles down a magnitude more quickly and reliably compared to the stock 19 - very noticeable. Compared to the G35 (9mm conversion), it was.... different. The 26 was more sharp and quick, while the 35 was softer and maybe slower. Hard to describe, but the comp definitely works. By the way, the G26 mag for at least one of the brighter runs was the MagPul 12 rounder which has the little pinky hold on there.

Mostly I had good ejection with the HST, but you will see brass hit me at least once, if not twice, on the right arm with the 26. Again, Apex extractor and an HRED in this gun. With weaker/cheap loads, still extraction that is just okay. I had no malfunctions, but my 15 year old daughter who is still trying to figure out grip and getting in behind the gun, had a few failure to ejects with the weaker ammo. Not unexpected, but it does validate the notion that the comp bleeds off significant gas.

So, still tickled with the KKM/Comp, but I definitely have to get the front sight issue sorted out.

Yup. What I wanted to do was go G27 with KKM conversion barrels in 9mm and 357 SIG, along with a .40 threaded barrel, all threaded for a .40 comp. That would truly be a do-all rig, but you would also be well past a grand deep on that - without an RMR. Too, I think KKM changes the thread pitch on the .40 compared to 9mm. (Their website is kinda sucky.) They could probably do a one-off on the threading, but now we are talking mo' money and lead time. So I "settled" since I already had a G26 which was mostly collecting dust. I'll just have to be content slinging 147 grainers down range at +P speed.

I have kinda sorta somewhat this setup with various non KKM barrels -- Lone Wolf, Storm lake, S3F along with a little Lone Wolf .357 comp. Can't speak for the .40 because I don't have a .40 comp. Shooting the 27 in .357 sig, as I'm sure everyone here is well aware, is pretty darn snappified. The comp does hold the barrel down noticeably and alleviates some of that snap. I would guess the KKM comp to be superior but I have absolutely no clue. I've yet to see one of those at the range to even grovel to shoot it. What amazes me the the most is how well behaved the 27 is regardless of what setup you throw at it.

Right or wrong I threw a little red loctite on the muzzle threads and blue loctite on the sets screws. Anybody got a take on this? Not needed?

I blue loctite the threads and screws ... and it is absolutely necessary for the LW comp, otherwise over the course of shooting a while it will begin to rotate. Not much, but it does get knocked a little outta whack. Red *may* be overkill.


Added: Also, you can play around with G23 threaded conversion barrels on the 27.. they will fit. Looks a little silly but are ridiculously fun to shoot. Much more fun than it should be.. ;-)

Critter - Blue Loctite is almost assuredly the way to go with the KKM comp. Still using the red (cause it's what I have). Last night when I wanted to make sure I had screwed the comp down as far as it would go (I had), I hit it with a heat gun for about 45 seconds and everything moved without much protest. That red sure does lock it down though.

It just occurred to me that I should have shot with the stock G26 barrel last night. Doh!! Maybe next time.

If I intended to carry it with a comp or set it up solely for competition I'd go with the red on the barrel threads. For me, all of this is merely range fun so it's far less than critical.

Apparently I am easily influenced. Just found a screaming deal on a lightly used BlackList barrel for the G26. Have an Alpha Wolf comp coming as well.

Doing some dry fire and I absolutely love the "-" connector and NY1 in this. I have been shooting a match hybrid LEM for a while and hated the Gen5 Glock I tried a few weeks ago.

I try not to shoot in the yard unsuppressed so it might be a few weeks before I get some range time with the comp. If it fits my G17 holster then maybe I can run it at IPSC next month.

It fits in my G34 holster which is one less thing to worry about. Hopefully get some AE 124gr and Ranger T 147gr through this weekend. IDPA is in 2 weeks but I am reading I cannot use a comp. I'll ping the RO and see if they care.

Ray - that is a pretty outrageous set-up right there! Curious to hear how she shoots. Ought to be pretty dang flat with all the ports on top.
ETA: You know, if you were really serious about this, you would have the front sight mounted on the comp, just to the rear of the first port where all that luscious, unused real estate is. Do it man!

Question for anyone who knows: I am probably going to throw a Wolff 14 pound recoil spring in the comped 26 based on the still weakish ejection (compared to the 19 and 34) of the HST loads. If it will let the gun cycle poofter loads more reliably, so much the better, but that's not the driver on this. Bad idea or not? I want to say I don't want to waste 30 bucks if this is going to beat up the gun or make it unreliable, but I'm far enough down the rabbit hole at this point, 30 bucks ain't gonna make or break this project....

Oh. I was able to email Ameriglo the other day and they confirmed that the GL-301 sight set uses a .220" front sight. FWIW, they returned my email within an hour or so. My intention is to put this thing on paper and see what it is really doing with POA vs. POI.

[Tensaw]

So yesterday I took receipt of a Wolff Guide Rod and Recoil Spring Assembly. The spring is rated for 14 pounds instead of the factory 16 pounds. I made this change in recognition that the comp is bleeding off some significant gas which caused the already sketchy ejection to get a little worse. My hope was that the increased slide velocity with the lighter spring would chunk out the empties with a bit more vigor. This ended up being the case. That being said, let me veer out of my lane and editorialize on ejection of spent casings in the Glock family.

I was previously aware of issues with BTF, but, like many things, this did not become important until I was personally affected. It was a few years ago and I was running the last stage of a day-long fun match with this same G26 in a stock configuration. It had been hot and sunny all day. I was hot (and sun-burned). The gun was hot. The barrel was hot. Everything was hot. The buzzer buzzed and I whipped out my gat and went to work. All was well until the last round of the first mag left the barrel. I felt the slide lock back and I started bringing the gun in for a blazing fast reload. Except there was a problem. As I bent my right arm to get the pistol into position for the reload, I had this pain - right on the inside crease of my elbow. It felt like.... well, it felt like someone had stabbed me through the arm with an ice pick. The spent brass had dribbled out onto my right forearm and when I went for the reload, I managed to trap that hot brass in the crease of my sun burnt elbow. It was quite unpleasant. It was at that precise moment that I began to study, in earnest, the ejection patterns of various pistols.

My observations on this are thus: 1. Glocks, generally, have some of the weakest ejection patterns of any factory pistol out there. 2. The sub-compacts have the weakest ejection patterns of the Glocks. 3. The 9mm Glocks eject less forcefully than the .40 cal models. I have also noticed that across all 9mm Glocks, that, if any round is going to eject in a way you don't want it to, it will be the last round in the mag that does so, although any round in the stack can go awry. So when you add all this up, the G26, as a model, is probably one of the worst for consistent, forceful ejection of spent brass. All that said, I was downright giddy when LL posted up his "Almost Guaranteed Fix for Glock Ejection". Upon reading that, I immediately ran out and started polishing extractors. The polishing and an HRED (previously installed) absolutely cleaned up the ejection on my 19. The 26, however, just sat back and laughed at my feeble efforts and continued dumping brass at my feet.

As another aside (and getting even further out of my lane - we are off-roading now), I suspect that the G26,with its abbreviated slide travel, poses such a challenge with regard to timing the ejection, that even Apex has not fully cracked the code on that extractor as evidenced by their statement that their fine offerings are not intended for the 26. I now wonder if, not only is the design/execution of the factory extractor sub-par, but if the 26 is not over-sprung at 16 pounds. I suspect Glock erred on the side of durability in the battle between that and functionality when it came to spring rates. The heavier spring probably saves the gun from being beat up, but at the expense of vigorous ejection of spent brass.

So with all that rolling around in what passes for my brain, I ordered and installed the 14 pound Wolff Recoil Spring Assembly. Upshot - it works. The comp-equipped G26 fed and ejected all rounds from weak Perfecta 115 grain loads (which previously reliabily stove-piped) to 124 grain standard pressure HST. The weak loads generally kicked out two or three feet at 3 o' clock with the hotter loads kicking out twice as far at the same position. I think the very first mag of the Perfecta had one (first or second round I think) actually eject *forward* of the gun, but it settled down after that. (I am unsure whether this was caught on camera.) Overall, I am pretty pleased with how the gun ran with the 14 pound spring. I'm not sure I would want to go any lighter than that with hot loads, even with the comp in place. You will see on camera how the load makes a difference.

One more thing. I used the "Slo Mo" setting on my iPhone to record my shots. Apparently, the Slo Mo function got stripped off when uploading the files to Google Drive (if someone knows of a way that I can get the Slo Mo version posted, let me know). But watching the gun recoil in slow motion, especially compared to a factory G17, also in slow motion, absolutely validated my seat-of-the-pants feeling that the comped 26 was shooting flatter then even a G34. The best way I can describe it is that the comped G26 recoil is a quick, light, snap where the bigger non-comped guns are a bit of a heavier, slower, shove. The big guns almost feel sluggish after shooting the comped G26.

So, with all the yakking out of the way (which was way more than I intended) I am going to post up links to the video. The point of the videos is to capture the ejection pattern of various loads. The Perfectas are brass cased and exhibited the weakest ejection. I also shot some 124 Blazers which also brass cased. HSTs have a silver casing. The longest video where I shoot two mags back-to-back has Perfecta (I think) in the first mag, and the stronger Blazers in the second. Since *this* post took longer than intended, I will have to leave and come back later to get those up.

[Tensaw]

This video probably tells the story the best. A few rounds of full power 124 grain Blazer followed by a second mag loaded with weak 115 Perfecta.

I believe these are the 124 grain standard pressure HST rounds.

Would it be feasible to attach the front sight to the comp?
In Enos' book, he talks about what a revelation in speed the sight on the comp produced. It not only lengthened sight radius, but the sight did not blur and disappear in recoil, it just hung there.

[Tensaw]

In its current form, the KKM does not have enough real estate to mount a front sight. I would love for KKM to produce a version with a bridge across the port closest to the muzzle where a sight could be mounted.

[rayrevolver]

Been slacking on this. I was able to shoot 5 rounds of AE 124gr FMJ at 50 yards and it shot/ejected just fine and locked back.

To be honest, I was not prepared for the blast and didn't shoot the stock barrel for comparison. In my own defense I shoot quietly at home now so this thing was an eye opener. Next range trip I will dedicate time to this as opposed to a PCC I have been troubleshooting. Also just need to get some rounds in prep for USPSA next month.

That said, any of you guys want to install a front sight on my comp, you are more than welcome. I'll pay shipping both ways. :)

Another comp option was released from HKParts for the P30 but should fit any 1/2x28 barrel.

[Tensaw]

Ray - I keep eyeballing my comp and wondering about the possibility of soldering a front sight on there - without damaging the adhesive that retains the tritium vial.... I kind of wonder if you don't have enough real estate to be able to mount one with a little judicious drilling.

Also, I like the size of that comp HK Parts has for sale. (I do have to question those huge side ports on there though.) Mayhem Syndicate alleges to have one in a similar size envelope releasing "soon" - but they have it listed for $300. No can do. Good looking design though.

I have contemplated whether we should start a thread listing/reviewing the various comps out there that are suited for concealed carry.

Post back up after you get some more rounds through yours and let us know how it goes.

Re: sight on comp.

So I have to think you would not want a port adjacent to the rear side (the part your eye sees) of the front sight because it would soot up after about one shot. This means it would need to be mounted behind the first port - the part of the comp closest to the muzzle. On the KKM, all of that area is taken up by where it threads on to the barrel. That's why I'm thinking solder on the KKM because you then would not have to penetrate the body of the comp and get into the threads. But again, if you could lay a strip of metal down across that first port (running parallel with the barrel), that would be a pretty good place to mount the sight. On Ray's, it looks like there would be some space forward of the threads, but behind the first port. On either comp, you would sure as hell want to hit Top Dead Center of the comp with the front sight.

I was sniffing around the idea of a comped 26 a few months ago, but on a 19 frame and with an overall 19 slide length for ease of holstering. I still wish this was possible... https://pistol-forum.com/showthread.php?40817-PMM%92s-new-320-comp-has-me-thinking-about-Glock

I’m a little ashamed to say “no.” According to my notes I put 50 rounds through it and confirmed my carry ammo hits to the dot, and then I started screwing around with the G48 and wondering if I would have been happier doing the whole project on a 48 or a 43X slide for my 48, and then we were into Covid lockdown.

I'm just shy of 1000 rounds through my Mayhem Syndicate comped Gen5 26 and it has become my favorite carry pistol by far.
With factory +2 magazines it shoots softer than my 19 and has a much more carry friendly grip profile.

I think the shorter barreled pistols benefit from comps more because there's more muzzle blast to redirect.
I can feel the difference between comp and no comp on my 26 more than I can on a 19 or 17.

So would you consider the upgrade of the Apex kit worth the price of admission? I have put them in a buddy's Gen. 3 19 but not tried them in any Gen. 5 guns. Been tempted to try the Wolff 6lb. striker spring swap but still waiting on my springs to ship after ordering them two weeks ago... 2020 I guess.
