Crimson Trace LG459 Laserguard 5mW Red Laser 633nM for S&W M&P Compact, M&P Shield EZ (Black Finish)

The Crimson Trace LG459 Laserguard is a compact red laser sight built for quick target acquisition on Smith & Wesson M&P Compact and M&P Shield EZ pistols. This 5mW laser sight mounts directly to the trigger guard and installs without gunsmithing—you can have it running in minutes. The front-mounted activation button uses Crimson Trace's Instinctive Activation technology, so the laser comes on naturally when you grip the gun, giving you a bright aiming reference whether you're training at the range, practicing defensive drills, or carrying for self-defense.

The LG459 is powered by a single 1/3N Lithium battery (included) that runs for over two hours per charge, making it reliable for serious practice sessions or everyday carry. The red laser dot is factory-sighted at 50 feet and prints at approximately 0.50 inches at that distance, giving you a precise aiming point. Best of all, windage and elevation are fully user-adjustable, so you can dial it in exactly where your rounds go from your preferred shooting position and distance.

Built from durable polymer with a rubber overmold for secure grip and weather resistance, the LG459 handles the bumps of range bags and defensive carry without complaint. The black finish blends seamlessly with modern tactical setups. Crimson Trace backs this sight with a three-year full warranty, so you can trust it to perform when it matters.
