The LG-499G Laserguard is a powerful green laser sight designed for the Heckler & Koch (HK) VP series of pistols including: VP9 VP9SK and VP40. Featuring a 5mW peak 515-532nm Class 3R green laser beam the LG-499G is operated by Crimson Trace’s famed Instinctive Activation which allows the unit to spring to life with a normal firing grip. This model features a front activation button. As with all Crimson Trace laser sights this Laserguard is easily user-installed in moments with zero modification to the firearm. It is factory sighted at 50′ but is fully user-adjustable for windage and elevation with provided tool. The LG-499G features a Master On/Off Switch for completely powering down the unit if desired.
