Ironically, the Gen 3 Glock 22 is the only Glock I've ever had reliability complaints about. Attach a weapon light to the front of one of those and try and shoot 180gr FMJ ammo through it and it won't get through a mag. We took the light off and it ran fine. Apparently it was a pretty common issue with them, but based on my prior Glock experience I'd have never believed it if I hadn't seen it with my own eyes. Something about the way the frame flexes under recoil, and how that's altered by attaching something to the rail. Supposedly it gets worse as the springs age.
The Glock 40 and WNL issue dates back to when Illinois State Police adopted them in 1998 ish. The Gen 4 in 40 suffered the same issuesIronically, the Gen 3 Glock 22 is the only Glock I've ever had reliability complaints about.

And I can’t prove this but I believe it’s more than likely one of the reasons Glock made the Gen 5 40 cal with a 3 Oz heavier and slightly wider slide.
I did not hear the specific lights mentioned however about every agency had the issues from Illinois to LA area and others. So I would probably be safe to presume several different lights could have caused the issue.Didn’t it also have something to do with the type of light? Lights like the streamlight LTR-1 people could crank down pretty tight.
