Crimson Trace Defender Series Accu-Grips Laser Sight -
Eliminate the guesswork of aiming accurately in life-saving situations with a laser sight that fits most Smith & Wesson J-Frame round-butt models or Taurus small-frame revolvers. Beam Lock™ technology allows you to adjust the sight for windage and elevation (factory sighted at 50 feet). Attaches to your handgun in the form of a grip replacement, and the top-side, red N'Gage™ activation button turns on the powerful, red laser with a 1/2” dot size. Runs on two 2032 batteries (included) for a total of two hours.
