So, my lil semi-auto hasn't seen much action lately due to scarce ammo and the fact that she seems to choke on anything but HV ammo. She will FTE, FTF and stove pipe. Might run 20-30 clean then jam up. Sometimes she'll choke right away. I've had her cleaned by a smith some 5 years ago. I did this because there are very few screws in the receiver, mostly metal tabs and I didn't want to damage anything taking it apart. Wondering if I should have the springs and firing pin replaced. Sometimes she'll strike and not fire...could be a squib but we're talking CCI ammo. Too many squibs for my liking. I'm trying to decide if it's worth spending the money to have her completely torn down and rehab'd by a smith or shelve her and replace her with a modern .22LR. Any thoughts? Edit: I should add that this lil gun belonged to my wife's grandfather and is likely older than I am.
