Has Any body heard of these? I have one that need some parts.It is in 45 acp and is very ruff, Jams on the 4th shot every time and takes a act of congress to get it free and the shell out. The catch pin is broke or i think thats is what its called,it holds the slide back and needs to be replaced, and it won't stay cocked when you pull the hammer back now. Any advice for this sick puppy.
