I have a 20 year old Walter (Interarms) PPK in .380 Auto. The gun has only had about 100rounds fired through it, mostly because it 'hangs-up' about ever second shot. I like the looks and feel of the gun and it fits in my leather peanut bag perfectly for MC carry. So I'd like to keep it. If anything can be done to it, I'd like it done in the hopes that it can become a reliable piece. Any suggestions or good gunsmith recommendations?? Thanks, Frog.
