Take your personal safety a step further with a laser sight that attaches to your handgun in the form of a trigger-guard attachment – no more guesswork involved when it comes to accurate aiming. Beam Lock™ technology allows you to adjust the sight for windage and elevation (factory sighted at 50 feet). The dual-side red N'Gage™ activation button turns on the powerful, 5mW red laser with a 1/2” dot size. Runs on either one 1/3N lithium battery (included) or two 357 silver-oxide batteries for a total of two hours. Available for: Glock 17/19, Ruger® LCP™ and Springfield XD/XD(M)™.
