Simply remove the existing grips with a screwdriver and replace them with your new Lasergrips. Lasergrips complement the original weight and feel of the pistol and are manufactured to the same exacting standards that all Crimson Trace systems are known for. The design locates the laser high on the grip panel, in close proximity to the barrel centerline. A pressure sensitive pad in the grip activates the laser, while a conveniently located master on/off switch allows complete operator control.
