The Fenix GL22 Tactical Light stands ready to become an important tool in your arsenal. Blasting 750 lumens, this pistol light can instantly throw light 591 feet with a simple tap of either the left or right switch. Perfect for left- or right-handed shooters. You can also choose between the white light only, a red sighting laser for quicker acquisition of the target, or have both on simultaneously. Plus you can disorient an assailant by holding the switch down to activate instant strobe. Easily attaches to full size (and some compact) pistols with a Glock or Picatinny rail. Impact-resistant and IP66 rated dust and rain proof, the Fenix GL22 Tactical Light is ready for any tactical situation. Rechargeable Li-ion battery is included. Will fit most full size pistols with a Glock or MIL-STD-1913 (Picatinny) rail. Will only fit a few compact pistols including the Glock 36, Sig Sauer P229, and Springfield XDs. Will not fit other compact models from Sig Sauer, Taurus, F&N, CZ, Springfield (Hellcat), H&K, and Smith & Wesson. Will not fit any sub-compact or micro-compact pistols.
