I’m looking for grips and a few odds and ends for witness t/p 40 and I’m not getting a clear answer as to what CZ models I need to look at parts for I’ve been told the 75. 75b. 75bd I really don’t know how different they are but in reference I’m looking at grips possibly a mag well as long as I don’t have to have any extensive gunsmithing done I would also like to replace the slide release with something with a little more surface area for me big old meat claws lol any help would be greatly appreciated thank you all in advance
