Availability: In Stock
The Crimson Trace LG457 Laserguard is a compact red laser sight built specifically for Smith & Wesson SD and SD VE pistols in 9mm Luger and .40 S&W. This 5mW laser projects a bright red dot at 633nM wavelength, giving you a dependable aiming reference for defensive shooting, low-light situations, and target work. The black polymer housing integrates seamlessly with your SD platform, and the 50-foot effective range keeps you on target where it counts—up close and in the moment when accuracy matters most.
Laserguard sights aren't about replacing iron sights or scopes; they're about adding a fast, intuitive aiming option to your carry gun. A visible red dot helps you acquire your target quickly, especially in marginal lighting or from unconventional shooting positions. The LG457 mounts directly to your SD or SD VE, turning your existing carry pistol into a more versatile platform without the weight or bulk of optics.
If you run a Smith & Wesson SD defensive pistol and want to sharpen your shot placement with a laser sight, the Crimson Trace LG457 gives you proven technology in a compact, durable package. It's practical gear for shooters who value speed and simplicity at close range.
