Crimson Trace Rail Master -
The Rail Master Laser or LED light locks on to most M1913/Picatinny and Weaver rails, and won’t budge thanks to secure-lock technology. A custom fit can be achieved if you have multiple recoil grooves on your rails, making this light even more universal amongst your handgun collection. Four inserts ensure an extremely wide range of fits. Easy and quick to move from one firearm to another in minutes. Simply tap it on and off from either the right or left side, and control the kind of light you need thanks to three light modes: momentary, constant and strobe (White LED light only). An integrated auto shut-off feature turns the light off after five minutes to preserve battery life. Made of tough polymer with a black finish. Batteries included. Full three-year manufacturer’s warranty. Made in USA.
