Crimson Trace LG-420 Laserguard Red Laser Sight for Sig Sauer P320/M17/M18 - Black Polymer

The Crimson Trace LG-420 Laserguard is a compact red laser sight purpose-built for the Sig Sauer P320 family of pistols, including the military-issue M17 full-size and M18 compact service pistols. The unit clamps directly to the factory trigger guard for a low-profile, integrated look and is NOT compatible with P320 Subcompact frames.

At the heart of the LG-420 is a high-visibility 633nM red laser rated at 5mW, factory-tuned to a 0.50" dot at 50 feet for rapid close-range target acquisition out to a 50-foot effective range. A single CR1/3N battery powers the unit, and the pressure-pad activation provides the instinctive, master-grip-controlled on/off Crimson Trace is known for - the laser comes alive the moment you take a proper hold of the pistol.

Built around a rugged black polymer housing and tipping the scales at just 1.60 oz, the LG-420 adds virtually no bulk to the host pistol. Externally accessible windage and elevation adjustments let you zero the beam without removing the unit, and the trigger-guard clamp design requires no gunsmithing, custom holster, or permanent modification to the firearm. Whether you run a duty M17/M18 or a carry-size P320, the LG-420 drops on and goes to work.
