The INSIGHT M3 Tactical Illuminator (GLL001A1) is in the holsters of more law enforcement officers worldwide than any other brand of tactical light. If you require light weight, rugged durability, and absolute reliability for your pistol's tactical light, you want the M3.

The M3's light is activated by a rear rocker switch that's easily accessible just forward of the trigger guard on your pistol. Whether you're left or right handed, all you need to do is move the switch up or down with the trigger finger of either hand. The switch has two positions: momentary or constant.

The Insight M3 Illuminator is also focusable, letting you adjust it to a broad beam or to a very narrow beam of light.

The patented Slide-Lock system allows you to quickly and securely mount the light to your pistol's rail.

Fits Glock, Beretta, HK, CZ, Sig, Springfield Armory, Kimber, and all other pistols with factory-equipped light rails. Universal or 1913/Picatinny light rails are available for most pistols that do not have light rails.
