Ken from florida - Crimson Trace Lasergrip For Smith & Wesson K/L Frame Round Butt LG306

Think it works well but grip is smaller than the original Hogue grip that was on the gun. It is a heavy gun so a larger grip makes it more controllable. Also was a little tricky to put on. Metal stirrup had to be removed first and lining up screws while keeping battery inserted correctly took several tries.
