The Crimson Trace LG-499G Laserguard available at Night Vision Guys 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.
