I picked up a Springfield Ultra Compact 1911 a couple of months ago and finally was able to shoot it the other day. It was used, but had very little wear. From the price I paid, I figured someone had had feeding/jamming issues with the gun and didn't want to mess with getting it fixed. Took it out to the range, and sure enough, it didn't want to chamber a round quite frequently. No set pattern. Field stripped the gun, it had been cleaned prior to shooting, nothing noticed as a significant burr or metal to metal contact. Reassembled and while working the slide I noticed that occasionally the slide would stick about 1/2 in from being fully closed. If I put my finger on the muzzle of the gun, it'd snap closed. Fired it a little more, same problem. Maybe less frequent, but not a whole lot. Looking at the top of the barrel/chamber area, there's wear from the rear locking lug on the slide.
If I were to take a lapping compound and run it on the slide barrel area, what would that do to the lockup? Do those have to have a sharp edge to lock up properly? If lapping isn't the right answer, what about lightly polishing the rear lug on the slide?
Secondly, more mags for the gun, can I get any 6-7 round mag and it will work? My 8 round Chip McCormick mags for my full size 1911 will cycle rounds same as the one 6 that came with the gun, but won't lock the slide back on empty. Not enough spring pressure after the last round.
