Crimson Trace Rail Master CMR-209 200 Lumen Weapon Light

The CMR-209 Rail Master is Crimson Trace's compact universal weapon light for rail equipped pistols. It puts out 200 peak lumens from a white LED, enough to identify a target across a room or down a hallway, and weighs just 1.98 oz with the battery installed.

It clamps to M1913 Picatinny or similar accessory rails and fits most pistols with at least 1" of rail from the recoil lug to the trigger guard; the same rail lets it ride on some shotguns and rifles. Activation is tap on/tap off with constant and momentary modes. The polymer body is water resistant (IPX4) and rated to survive a 1 meter drop, and runtime is about 1.5 hours.
