I inherited my grandfather's M1922 pistol. The interesting thing about it is that it is the version that was made by the Nazis when they overran Fabrique Nationale in 1940. It has the Nazi proofs on it to prove it. Anyway the problem that I have found is that I think one of the springs in it for the slide is way past its prime. The slide moves back no problem but fails to lock. It fails to hold when pushed back and everytime I do it immediately goes to its default position. When I tried to load it at the range it would not even chamber the round and wound up getting jammed until I forced it out safely. Any advice you could offer me? Is there a site or somewhere where I can find replacement parts because I have been looking at gun shops and gun shows and no one has them.
