Crimson Trace LG-420 Laserguard Red Laser Sight for Sig Sauer P320 M17 M18 Pistol

The Crimson Trace LG-420 Laserguard is a red laser sight designed for the Sig Sauer P320 pistol, which is also designated as the M17 in full-size and M18 in compact configurations. Installation is straightforward and requires no gunsmithing, with a front activation button that uses Crimson Trace’s Instinctive Activation technology. A single 1/3N Lithium battery powers the sight for four (4) hours of runtime, and the quick change battery cover allows battery replacement without removing the unit from the firearm. Like all Crimson Trace laser sights, the LG-420 offers complete user adjustment for windage and elevation. This sight is compatible with all P320 models except subcompact frames.
