Much like our full-size M&P Series Lasergrips for S&W pistols, these are interchangeable between different calibers of compact M&P pistols and feature a hard polymer surface that's most closely matches the medium stock Smith & Wesson grip inserts. These lasergrips fit the M&P pistol just like the stock grips while offering a compact laser diode housing that's well suited to most carry and duty holsters. They also feature a rear-activation switch that's part of your natural grip so there's no fumbling to activate the laser with your trigger finger.
