I pulled this NcSTAR Pistol / Rifle Laser Mount Set APRLSS off my son's handgun and mounted it on the top rail of my HiPoint 4095 carbine in .40 cal. I took the gun into the mountains to do some plinking. Fired approximately 100 rounds through it using a red dot site and ignored the laser (The sunlight was too bright for effective use).
When I got home I noticed that the laser barrel had shifted in its mount. The recoil of the gun had shifted the laser barrel so far forward that the on-off switch bar bumped into the mount and bent backwards. I thought the laser was ruined.
I loosened the grip bracket (middle allen screw) on the mount and slid the laser back. With needle-nosed pliers I carefully bent the switch bar back as straight as I could and turned it on. THE LASER CAME ON!..., I set the laser barrel back in place and this time I tightened the grip bracket with a little more effort to keep it from shifting the next time it was fired.

The laser barrel stayed in place this time, the light stayed on during the firing and did not shift its point of aim at all.
