OK guys, just bought a CZ 40P off gun broker. Never heard of one until 2 days ago. Never been a fan of the 40 cal but just had to see what it was. I've been told that it is pretty much a PO 1 frame with a PO 7 40 cal slide. I do not know. The gun has a lot of finish wear and I do not know what it looks like inside. I looked on CZ USA site and they list a slide stop for the gun and that is all they list. Does anyone know about part compatablity with other CZ's. Any help you guys can give would help.
