So ì have a tlr 7 light and it's survived about 3000 rounds so far and still in perfect condition. I recommended it to my friend, and his tail cap has broke off 3 times, no idea why, no clue what's causing it, therefore I'm not sure how to fix it.
I also recommended a holosun red dot for him, blue locktite and torqued properly myself, and the screws still came loose. I did the exact same with my set up and I haven't had a single issue.
Anyone know how to fix these problems or what's causing them?
They're on a Sig p320 V-Tac. It's a full size handgun with the x series grip.
