Glocks and Rail Mounted Weapon Lights

I've heard and read of some accounts of the Glock 22 having frequent stoppages when a weapon light is mounted on the rails.
My questions are: is this a common occurrence, and has it been sorted out (ie: is there a certain generation to avoid to not have this issue)?
Thanks in advance.

maybe because the light is attached too tightly and bends the frame, but then again.

ive shot glocks with lights attached for years. 10,000's of rounds. no problems at all.. and i cant see why it would be purely the g22 as they all share basically the same frame.

I can't see why. If anything, the added weight up front would help control recoil and aid in combatting ejection stopages due to lack of recoil control.
 
Not something I've ever noticed over several thousand rounds. Sounds like someone trying to sell you a different pistol.

It's not uncommon. Our PD tried out X200 and TLR-1's. We settled on the TLR-1 as it was the most popular feature wise with the members. Since issuing them, I have noticed an increase in fail to feed stoppages. This can usually be remedied by going to new mag springs (11 coil). However, adding a light to your Glock changes the way the gun flexes. As it can't flex on the dust cover as much, the energy transfers to the feed way area, causing some stoppages. If you weak wrist, it's even worse. Having said that, some people have absolutely no problems regardless of age or round count in the pistol, which generation mags they have, or whatever. We have X200's in service with some units, and I do notice more stoppages with that light. I suspect it's because the light has more contact with the rail. If you search it, you will find some cases where US PD's have transitioned back to no tactical light due to this issue.

Nice info, have you guys noticed if the particular light that caused problems was very tight on the rail?
 
I've seen it happen with tight light's as well as some ready to fall off. With the TLR we teach to tighten the locking screw as tight as you can with your fingers, then give it another half turn with a coin. This will keep a TLR on a Glock consistently, but they are taught to check weekly. This seems to be more of a problem with the newer aluminum bodied light's, as they are more rigid. The plastic light's (M3, M3X, Glock etc...) don't seem to have the same problems in my experience. We are using G22's mostly.

Record for thread revival...?

Couldn't find any newer threads covering this topic. Question I have is for any of you fine folks who have a gen 3 g22 with a weapon light WHO HAVE NOT MODIFIED said gun (or mag springs). My work issued gun can't be tinkered with...

Any luck with the Inforce APL as opposed to the likes of the TLR1 etc?

No issues on my gen 3 with a TLR1...several thousand rounds...
 
As was mentioned earlier, the only issues I have experienced(with others guns) have been with cheap lights needing to be screwed to the rail. The simple overtightening caused the frame to narrow and prevented the slide from coming into battery. Some folks try to crank down on the screws/nuts creating their own problems. Havnt had a single problem with a properly tensioned device.

I haven't heard of any agencies that have adopted the Inforce APL that still use the Glock 22 Gen 3, so any data you get will probably be examples from individual users. From everything I have seen regarding this, does not seem to matter what light is used, to include the Glock light.

The failure to feed issue caused by adding a light is due to excessive slide velocity. The magazine can't keep up with the slide during the firing cycle, and as a result, the rounds do not get fed up into position in time to feed correctly and the nose of the round gets pushed into the front of the magazine body. This is caused by the stiffening of the dust cover, which does not flex as much, thereby allowing the frame to travel faster, due to less friction.

Does not being able to "tinker" with your work issued gun extend to magazines, or internal parts of the magazines?

Fixes that I have seen for this issue, apart from upgrading to the 22/23 Gen4, or changing to any current gen of the 17/19, are as follows:

1. Use the latest generation magazine followers.
2. Use 11 coil magazine springs.
3. Use newer magazines that contain fixes 1 and 2.
4. Replace the recoil spring assembly at least every 2000 rounds.
5. Use standard pressure 180gr loads running at approximately 1000fps.
6. Loading the magazine down by one or two rounds.

Regards.

Thanks. Hopefully just a pressure issue.

Basically only allowed to clean and feed the beast and that's it. I'll look into what gen mags we're using.

X2... just took my TLR1 off after my last range day due to issues with fail to feed. No issue with full power duty ammo, but training rounds, not so much.
