Potential issues with Glock rail/light interface?

[MOT]

Does the regular swapping of the light on and off the rail cause any issues over time? I have a couple of streamlight TLR1HLs that get shared time on a few different glocks. I don’t use a wrench to tighten them on. No problems so far, just wondering what don’t I know.
Thanks for any help in advance guys.

If you over tighten the screw, you can flex the frame and cause some issues. My PD had to buy some new frames because a few guys went gorilla on the X300U-B screws and bent the frames.

The easy fix is to get another TLR-1HL or two, they're pretty inexpensive.

We have guys that take off and remount the light almost daily with no adverse effect.

I have put a light on a gen 3 Glock every night for over a decade. Finger tight with no problems. Long ago it was the Glock brand light. ( To date myself ) For the last 6-8 years it has been a Streamlight TLR1.

Only one issues we’ve seen is on .40 caliber guns and the frame not flexing as far as glocks go. 9mm no problem. .45 no problem.

How about 10mm? Had a hot bear load knock the light off once.

I have zero experience with 10mm sorry.
