Well, gosh, it's too bad someone didn't recommend removing the big electronic tumor before.

I thought the “long screw/extractor” issue was only in the slim lines.

One thing I have subjectively noticed on newer Glocks is they seem to have increased the RSA weight. They all FEEL tighter so to speak. Not sure if this would be an issue but itty bitty gun, extra weight on top and oversprung is a recipe for a “break in”

That said I would expect stove pipes or FTRB or something like that.

Will the gun hand cycle reliably?
Is the “stripper rail” getting back far enough to push the round out of the mag? If not the mag might just be pushing the new round up and slightly out without the rail getting a hold of it to push it forward into the chamber.

As was said first thing I would do is remove the optic and test. It’s all about removing variables. Also, while I am FAR FAR from an engineer of any kind choo choos to bridges , I have to believe when we cut legacy firearms for optics and Glock sure is legacy at this point, we introduce forces the engineers never imagined at the time and a slightly out of spec RSA combined with the optic might be enough to throw the system out of whack. Weapon lights and Glock 22/23’s back in the day come to mind.

Good luck.
Take care, shoot safe

If the screws used to mount the plate are to long they can make contact with the extractor plunger. This can mess up the cycling of the gun. I had the same issue in a Glock 45. As soon as I replaced the screw with a shorter one the problem went away.

The screws are fine. I did not use the supplied Holosun screws. I used a DPP titanium mounting plate and they ship the correct screws for both the Holosun and Trijicon RMR. I have the same plate on my other two Gen 5 guns.

I am going to detail strip, clean, relube, and try some hotter ammo. Every post I read with people having the same issue was told by Glock to give the recoil spring time to break in as they are much stiffer on the micro guns .

Thanks for all the help guys. I have been shooting glocks since my first one purchased in 1994. I’m not limp wristing and think this may just be a break-in issue. They can happen……even in Glocks. Anything man made can have issues.

Maybe try running it WET so to speak vs just the typical “drops” so to speak.

I have reason to believe you're getting good advice about the screws.

Just try the pistol without the sight mounted and see what you get.

Agree.

Or contact Holosun and have them send you the correct screws. There is nothing wrong with the pistol.

This ^^^^^^
It’s a common problem. I’ve seen many times with people who bring freshly mounted optics on their Glock to sight them in right before a match. As others indicated the one screw is too long and impeding the plunger from moving. I’ve also seen folks put way too much Loctite on those screws and it gets in the channel and gums up that plunger for the extractor.

You can test that theory while the dot is mounted to try and disassemble the slide cover at the rear and pull the plunger and spring out. I guarantee it’s jammed in there because the screw is tight against it.

That sounds like a good way to test if the screw is the problem, but you'll note that usncorpsman stated he did not use the stock Holosun screws.

If you used loc-tite, like your Holosun instructions suggest, and you didn’t put the tiniest amount on just the screw threads only, the loc-tite will go all the way into the EDP channel and your extractor will not work anymore. I made the mistake of putting a drop in the holes on the slide while mounting Holosun SCS’s on 20 department issued Glocks and caused about 14 of them to no longer function. I did take the opportunity to replace the Holosun screws with Battle Worx screws while cleaning out the loc-tite. No more issues now, but my mistake could’ve cost way more than money.

So, class, do we see the dangers of fucking with an established, smoothly-functioning system? Drilling holes into the extractor depressor plunger channel? Tickling critical parts with screws which have no place there? Seizing up the EDP spring with metastatic Loc-Tite goo from the big electronic tumor?

Baaah!! Madness!!

It's not the pistol optic's fault that the only way the Glock design can support it is by drilling a hole into the extractor channel. Pistol optics are an actual game changer allowing people to shoot with both eyes open and stay focused on the target. I practice with both optics and standard pistol iron sights and there is no question that the optics give me a distinct advantage.

That's not what I said.

^^^This.

Might I suggest field-stripping your G26, and checking your extractor to see if it moves? You can do this with a small punch. From the inside of your slide near the firing pin, push the extractor away toward the outside right of the slide. The extractor should move a few millimeters. If it doesn't move or moves with great difficulty, Loctite has likely frozen up the extractor depressor plunger's interaction with the extractor.

Along with the others, I would definitely encourage you again to please check the length of the DPP screws you used to mount the Holosun.

Our local college PD had similar malfunctions with their new G45 MOS pistols and we were able to trace it back to too much Loctite and over-length mounting screws. In the rare case that a Glock has a problem, my experience has been that it can almost always be traced back to a non-OEM part or parts.

Good luck and let us know how it goes.

Yes, sir! Actually, every time!

I've got 3 Glocks currently running optics with no issues and we just finished the T&E program at work on optics for the new duty weapons (Glocks) with no issues. I called them gimmicks for years, but now that I have old man eyes I've changed my tune.

I did have a Glock 26 that flat wouldn't run when I first got it. FTF every other round. Spring was way too tight. Left it locked back for a couple days and then shot a bunch of 124 +P through it and it's been flawless ever since even with the wimpiest 115 ball. Only Glock I ever had the slightest issue with, which is good because when I called Glock they couldn't have cared less about the issue and just told me to "shoot it and break it in." I'm sure I just caught a support guy on a bad day, but it left a bad taste in my mouth.

This stuff kills me. Let me ask you- what happens when you install a new RSA? Are you back to Malf City?

Don't know. Never replaced the spring once it started working and my other 26's spring is well broken in and ran fine when I swapped it in. Thats the whole reason I feel comfortable that it is fixed even though Glock didn't seem interested in taking a look at it. I'm at about 500 rounds of 115 WWB without an issue (plus a couple hundred mixed 124 and 147). I'm pretty sure I just got an out of spec spring. I'm not exaggerating. When it came out of the box it was a single shot firearm. Now I'm planning to get it approved for off duty carry.

Thanks for all the replies. I have checked the screws and extractor and all is well. There are also no aftermarket parts in my gun. It is all factory with the exception of the Holosun and mounting plate with are actually thinner and weigh less than the thick factory plate.

I spoke with Glock yesterday and was told the Gen 5 26’s have a very strong RSA and MAY need at least 500 rds of 124gr ammo to break in. If not functioning then, they would be glad to look at it. I am going back out tomorrow to shoot it again. The storm here in Florida and work have kept me from getting back out. I’ll update tomorrow after the range.

Glock has had its own issues in the past. Don’t believe all the marketing. I remember the bad extractors in the early Gen4 guns. Even Gen 3 had issues develop over time which is why they ultimately ended up redesigning not just the trigger bar but also the firing pin block safety.

If it ends up not working out, sell it and go buy a P365XL or P365X with a Romeo X Compact sight. Incredible package. I’m using the Romeo Zero Elite on mine and it’s been a very reliable and accurate pistol from day 1. Hope you get it resolved either way. It sucks when the pistol you’ve picked for carry has problems.
