The Fenix GL23R Weapon Light is a great accessory for your full-sized pistol. This light features three lighting modes including a 1200 lumen white light, a green laser, and the ability to use both at the same time. Why a green laser? A green laser is much more visible in the daylight vs. a red laser, giving you the added security of acquiring a target quickly in all conditions. Ambidextrous switches allow you to activate the light with either hand and the mode dial allows you to select the lighting mode easily. A rugged build along with a built-in USB Type-C charging port rounds out the features of this must-own weapon light.GL23R Weapon Light CompatibilityWill fit most full size pistols with a GLOCK or MIL-STD-1913 (Picatinny) railWill only fit a few compact pistols including the GLOCK 36 and some Springfield XDsWill not fit other compact models from Sig Sauer, Taurus, F&N, CZ, Springfield (Hellcat), H&K, and Smith & WessonWill not fit any sub-compact or micro-compact pistolsThe farthest rail notch cannot be less than 1.6875 inches from the trigger guardSpecificationsMax Lumens: 1200Max Beam Distance: 787ft (240m)Max Runtime: 1 hour (white), 13 hours (green laser)Lighting Modes: Three lighting modes including white light, white light and green laser, and green laser onlyBulb Type: Luminus SFT40 LEDLens Material: GlassColour Temperature: Around 6500KSize: Length: 3.43 (87mm) Width: 1.18 (30mm) Height: 1.69 (43mm)Weight: 4.23 oz.
