Good value, accurate, minor design fault. - ArmaLaser Laser Sight for SCCY CPX

Easy to install, good instructions, nice custom fit for my SCCY CPX-1 and easy to fine tune for dead-on accuracy. However, to turn ON the unit, you slide the master switch forward. But with my first firing, the recoil shock would kick OFF the master switch! I had a faulty switch; the switch was too easy to slide to the OFF position. I called the ARMALASER techs to discuss this and they sent me a new unit the same week at no charge. Replacement unit is identical, but the master switch has more friction. New unit is still working fine after 200+ test rounds. Permanent solution? The master switch should be designed so it turns ON when slid back, then recoil would never turn it OFF by accident!
Pros: Good value, accurate, easy to install & use.
Cons: Minor design with master switch, see comments.
