While we're paging 1911Tuner, I have one for him too (or anybody else with ideas).
SA Milspec 5", both Colt 7rnd and SA 7rnd mags. Bought new, ~1500 rounds down the tube.
Always had a problem going into battery...gets stuck last 1/8" to 1/16" from time to time with extractor over rim. All mags do it. Less often with FMJ ball, more often with SWCs. Almost like the slide runs out of steam before fully in battery. This happens with rounds that easily drop into a case gauge or into the chamber with the barrel out of the pistol.
Also had a problem with rounds jamming when nose-diving into feed ramp, but this is less common.
Recently started having the last round or 2nd to last round just pop out of the mag prematurely and fail to feed, and several end up in the chamber ahead of the extractor. Started getting double feeds.
Ejection is fine. 3-point jams are rare.
What I did:
Took a Dremel with rouge and felt wheel and polished the feed ramp. Adjusted extractor tension...it was very tight previously, now it just holds a loaded round. The extractor itself looks good with the radii where they should be and no big burrs, so I left it alone.
At the range I had no more problem with the last or 2nd to last rounds hopping out of the mags, but I had several (230gr MBC Softballs) end up in the chamber ahead of the extractor. SWCs seem to feed fine.
So, what else can I try? New mag springs? Stronger recoil spring? Give up and send to the gunsmith for the custom work I really want?
I think that the main problem is that the gun is just poorly fit together. It seems too tight...the rear left slide rail is wearing faster than the rest, the barrel link seems a little too long and feels like it's camming the barrel into the lugs the last 1/8", and the headspace is a little long...the barrel hood stands off the breechface by the width of a playing card, and loaded rounds are held off the breechface by extractor tension. It just seems like there is so much resistance to the slide coming to battery that if the round is a little snug or has any damage to the rim, it fails to go all the way.
Thanks for you help!
