Has anyone done this? I'm interested in replacing the stock 22 lb. one with a 19 or 20 pound Wolff one to lighten the double action pull somewhat. The pin in the hilt, although different in construction, looks similar to a 1911 setup. As long as I use a punch with a cupped end so as not to damage the pin, and I make sure the hammer is not cocked, do I just drive this pin out? I just want to be sure before I break something. Thanks.
