The issue with the lights is only with the G-22. It is well documented. We run roughly 500 G-22's at any given time. A signifigant amount that ran lights had issues. The same issue was noted within agencies throughout the US with the Gen 3 G-22. Not all will have a problem but it is a definate possability.

It was enough for us to switch to a newer gen three, which still had the same problems and a few more and then a gen 4. The Gen 4's are plagued with problems with the recoil springs and connectors. Bar none the worst batch of triggers I have ever seen. Most were 9-13 LB triggers and they were supposed to be 5.5. It has been a pita. Everu time I go to teach we end up switching parts out before we let them shoot to fix one problem or another. I am a fan of glock. Bu the last gen 3's and 4's are not to the standard I have become acustomed to over the past 20 years.
