.380 Colt Mustang will not fire
My Colt Mustang in .380 that I've owned for 25 years will no longer fire. It lay dormant for 15 years until I needed a lightweight CCW recently. I cleaned it and carried for a while. Went to the target range to test it and it wouldn't fire. So I stripped it and cleaned. Still wouldn't fire. Removed firing pin and it appears to be in good condition. Is there a possibility I'm mis-assembling the gun? When I re-assemble the gun I pop the ejector back up where it seems to belong. The gun will chamber and eject rounds with no problem, just the firing pin will make no mark on the primers. Just thought I'd ask here before searching out a gun smith.
