The Crimson Trace LG435 Laserguard KelTec PF9 Red 633 nm fits seamlessly onto the trigger guard, placing
the laser diode directly under the muzzle. The polymer housing has a
front-located rubber overmolded pressure pad which activates the laser when
the gun is held in a normal firing grip. Fully adjustable for windage and
elevation, the Laserguard can be fine tuned by the user and will run
continuously for four hours on one 1/3N battery.
