I bought a Pardini SP New Rapid Fire pistol this past September as an upgrade from the Walther GSP I was using. The GSP worked, I had pushed into the high 570s with it, but it was time for a dedicated .22LR RF pistol.
After I did all the initial setup that you normally do with a new pistol, I determined that the grip angle was still too severe. I had the grip cut to fit my hand just fine, but when I lifted the gun, the front sight was way above the rear notch.
I decided to go the route of changing the angle of the inlet, rather than reconstructing the entire grip from the outside. What follows is how I accomplished that.
