My Camper was made in 2000. It has a plastic firing pin housing as I believe all Buckmarks of that era do. I'm pretty sure they still do. The plastic housing because it's contained in the slide is pretty well protected and has never given me any problems over several thousand rounds fired - I consider this intelligent use of plastic. The slide buffer is of course plastic and it will wear out in time, but it seems to have a long useful life. I can't speak for plastic on other models
