The gun in 22 years old, but has only fired 100 rounds or less. It's always had some kind of a problem. First, with jamming. Better ammo has seemingly fixed that, but now the slide won't reset the hammer for the next shot. It has truly become a single action, where after each shot is fired, the hammer must be manually cocked for the next shot. On the rare occasion where the slide does reset the hammer, heavy breathing can cause the next chambered round to fire! If you, or someone you know is familiar with the old PPK (Interarms), I'd appreciate hearing from you. Thanks, Frog.
