Use a hammer on it, otherwise, you might be tempted to shoot it, the firing pin will break, and then you might be tempted to spend money getting it fixed....:tee:
back in the day, a place called Bobs Gun Shop, someplace there in north central AR, was about the only place in the U S that actually had any parts for those import guns. He was still alive at least until a few years back, but he has to be older than Noah at present if still alive. Still has a web site, but I suspect a son or different owner has the place. I used to deal with him on occasion in 1976, I was only 20 at the time, I always presumed he wasnt a pup then.
But every part he had, started at about 10 bucks, even then. Grips for example 10 or 15, when the guns had sold not many years previous, for under 30.
