The Crimson Trace LG-459G Laserguard transforms the S&W M&P Shield Plus into a precision instrument with instant target acquisition capabilities. This green laser sight delivers 5mW of Class IIIa laser power, providing visibility up to 2 miles during daylight conditions and exceptional clarity in low-light scenarios.

What Makes This Different

Unlike traditional iron sights that require perfect alignment, this Laserguard projects a precise green dot directly onto the target for instinctive aiming. Green laser technology offers 5x greater visibility than red lasers to the human eye, making target acquisition faster in bright conditions. The unit mounts directly to the trigger guard without requiring gunsmith installation or permanent modifications to the firearm.

Key Features

  • 532nm green laser provides superior daylight visibility compared to red alternatives
  • Instinctive activation via front-mounted pressure pad during natural grip
  • Aircraft-grade aluminum housing with matte black anodized finish
  • Four-hour continuous runtime on single 1/3N lithium battery
  • Adjustable windage and elevation with included hex keys
  • Master on/off switch prevents accidental activation during storage
  • Fits most standard holsters designed for M&P Shield Plus
The laser maintains zero through hundreds of rounds, withstanding recoil forces and environmental conditions that would affect lesser optics. Competition shooters report faster split times on multiple targets, while law enforcement appreciates the deterrent effect and accuracy improvement in high-stress situations. The unit operates reliably in temperatures from -10°F to 120°F with IPX4 water resistance rating.
