No overtravel of the hammer anymore. Fits in the most RNV without the lock in the grip frame.

  • Thread of the screw is metric: M3
  • Allen wrench for the screw 1.5mm

The grip frame needs minor modification to have space for the stop and the adjustment screw. Round file or end mill 1/4″ diameter recommended. I recommend using a 1/4″ endmill. That keeps the stop in place from sliding forth and back. I also recommend using blue Loctite to secure the screw.

While this part is easily installed, it is not drop-in, it requires fitting by a competent Gunsmith.
