View Full Version : TLR-1 light - any compromise of G19, G23, or G21SF reliability?
I've heard some reports of the use of weapon lights causing jams on some G22 models.
Is there any evidence of any reliability problems when using the Streamlight TLR-1 weapon light on a G19 or G23 or G21SF (all last years/3rd gen models)?
Or, are these light/gun combinations pretty much stone cold reliable?
My agency issues the TLR-1 and TLR-1s along with a variety of .40 Glocks. We have experienced malfunctions with the light mounted on well used G22's and G22C's but as long we swap out old guide rods (and springs) for new on a regular basis the malfunctions go away. I have a TLR-1 on a G23C and a G19 and have never had an issue.

I run the G30SF and G21SF with the Insight WX150 lights and after a few thousand rounds on both guns I've yet to experience one problem with either gun. I've upgraded a few parts though so I cannot attest to the reliability of 100% factory stock guns.

Run em on my 17's and 19's without issue.
Two G19's , both approaching 3000 rnd mark. One with the TLR-1 and the other TLR-1S. Both with the original guide rod/recoil spring assembly. No issues.
Good news to hear from you guys. Thank you. I've only had limited shooting time with my G19 and the TLR-1. About 30 rounds of 127 gr. +P+ Ranger RA9TA and all went fine. Will continue the testing with other ammo and my other guns.
Both my Gen. 3 Glock 19's run perfectly, with attached Surefire X300's. I don't see why it would be any different with TLR-1's. Can't tell you firsthand about 23's or 21's.
I have a TLR-2 on my G19, about 500 rounds down the pipe, no failure of any kind. (Low round count, I know.)
My question is, how does an attached weapon-light cause failures?
While my 21SF's run fine with either light, and the 9's seem to be the least affected by lights, I would still go to the range with the light attached and the ammo you normally shoot just to be sure. While my department is a relatively small sample, I have seen enough to know one thing...you never "really" know until you check for yourself...

No issues on gen 3 G19 and G17.
My duty Glock 21SF with the TLR-1 has over 10K rounds through it with ZERO problems. My department's issue ammo is the Federal 230gr. HST +P.
My off duty Glock 20SF also has the TLR-1 and has 6K rounds through it also with ZERO problems. I load it with Winchester 175 gr Silvertips.
So far, so good. :)
The problems you are talking about were specific to the Glock 22's. The lights would change the timing between the action and the magazine to the point that it would induce a malfunction.
The solution from Glock was to change magazine springs (from a 10-coil to an 11-coil). This made the speed of the next round being fed from the magazine more reliably match the speed of the action.
I worked through this problem directly with Glock on my old G22 duty gun. For the past three years I've carried a G21SF with a TLR-1 and had ZERO problems.
Hope this helps.
G19, TLR1. Couple of hundred rounds with light mounted. No issues.
Took CHL class with it mounted, also no issues.

Good with 9mm and .45 ACP Glocks, both TLR-1/TLR-1s and X300. Can't vouch for the .40 S&W models, though -- as I don't have any Glocks in .40 S&W.
If I were to pick up a Glock in .40, that's where I would look to the Gen4 models.
anyone have any fix for the jams caused by a tlr-1 on a g23? i called glock and they said they would call me back, but they haven't done so yet.
I have the number 8 followers on my magazines. Do I need new magazine springs? a new recoil spring? Anyone have any tips to help?

9x19mm Para Glock pistols both Fullsize and Compact should be %100.
.40 S&W is usually %100 with Gen3, but I would rather go with a Gen4 model with the most recent spring assembly.
Good luck.
No issues with any gun running a TLR-1, in my experience. I read the same reports of malfunctions with some .40 Glocks, but have never actually seen a failure attributable to a light. Seems like the additional weight of a rail-mounted light would only tend to make the gun a more stable platform for extraction and ejection. If that's true - and it may not be true - I never understood the potential problem.
The TLR-1 is a great value in a weapon light, by the way.

Yeah, I'd never seen the failures before I actually got my light. Haha, Every two rounds or so is a FTF or a FTE with the light on, the gun runs flawlessly with the light off.
From what i've read, the light makes the frame a bit more rigid, which then increases the slide velocity, which then translates to the magazine springs which aren't able to push up the rounds fast enough.
Ran my 19 in a class with the TLR-1 attached without a problem.
I believe the problem is only with the .40 cal glocks.
I dont have a TLR light, but my G22 with a X300 has operated with no issues with the light mounted.
finally got a hold of glock. They're having me send in my magazines. They're going to install the 11 coil springs for me. He was sure that would be the fix.
The first rep I talked to told me it was my recoil spring. But the magazine spring makes more sense.
Unfortunately I have rather extensive experience with this issue.
The Glock 9mms and .45s are GTG. The 3rd gen G22s and G23s made since the winter of 2005-2006 are a crap shoot due to the frame redesign that occurred then.
Awad,
This could easily be your recoil spring, as the issue is excessive slide velocity. If you have more than 2000 rounds on that recoil spring I’d swap it out.
interesting. I've only shot around 1000-1500 rounds through it. Would you go with a heavier spring or a lighter one?
I guess if its increasing the slide velocity, would a lighter spring just make the issue worse. Whereas a heavier spring would slow it back down to make the feeding more reliable.
Am I in the ballpark?
I have over 4000 rounds through my Gen4 G22. 1000 of those rounds were with the TLR-1s attached. I have had no problems at all.
I can only speak for the G19 with a TLR-s, but add me to the long list of no problems. Of course, if you are going to count on anything for defense, test your own pistol/light/ammo combination to make sure.
I had issues with my g23(3rd gen). I had the issue with a tlr-1 and glock light. With no light no issues. Even after sending it all back to glock the issue was still present. When the light wasn't attached there wasn't any issues. Anyhow, I've sold both my g 23 and xd tactical .40 so not sure how to completely get rid of the issue.

Yeah, I've just been looking at the m&p .45. this whole situation doesn't fill me with too much hope with it being resolved. The fact that it randomly affects some guns but not others makes it extremely difficult to get a fix that works for everyone.

I have run one on my G19 (3rd gen) and G29sf. I can't remember ever having a FTF/FTE with it on. FWIW, my typical loads are 147gr. ~ 980fps in the G19, and 200gr. ~1050 fps in the G29. My TLR-1 is "stored" on a G19 loaded w/ RA9T as one of my HD handguns.
