Budget buy - AimShot KT6506G43 Ultralight Red Laser for Glock 43

This product will serve the purpose if you are just looking for the look of a trigger guard laser and not actually the functionality. The laser itself works fine. The issue is the casing & support for the laser. I'm well aware every laser needs to be calibrated after use but this laser needs to be calibrate literati after every shot fired. I own two of these one for my glock 43 & one for my m&p shield i bought the second in hopes i bought a bad one and didn't want to give up on the company at such a low price but same quality both times. My friend also owns one of another brand that I've tested and after one day at the range i had minimal adjustments today while my aimshot laser looked cross-eyed after emptying two magazines. No i wouldn't recommend this product
