Great laser, easily adaptable to firearm - Crimson Trace CMR-201 Rail Master Red Laser Sight w/ Universal Mount

The CMR-201 Rail Master Laser Sight was easily mounted on my S&W SD9VE as the unit came with the exact spacer required for my pistol. The laser took very slight adjustments to properly align the windage and elevation when firing at 50 ft. The configuration of the dual power on/off makes it easy to use when shooting with either right or left hand. I especially found the spacing from the trigger to the power switch be perfect for my SD9 making it simple to quickly activate and acquire the target. This is a well-made laser for the money that definitely enhanced my shooting ability.
