? On feeding SWC's to a semiauto

Ian,
I am not saying this to just be contentious, but YES, a 1911 headspaces on the case mouth.

Take a case, and hook it under the extractor of the dismounted slide, and start sliding feeler gauges under the
head, between the breech face and case head if you want to see the ridiculousness of the often claimed
"1911s headspace on the extractor" story. Measure a couple hundred 1911 cases, you will find none short
enough, even with a massive crimp, to get to the extractor when chambered. I will allow for
the possiblity, because I have not actually tried this - PERHAPS you can put enough roll crimp
on a case to shorten it enough to get to the extractor, but I am quite doubtful. Even a
very tight TC and very short case is nowhere near getting there.

Most 1911swill have .030 or 0.40 or even more when held fwd against the extractor. You will never find a case short
enough or crimped enough to push in anywhere near that far, no matter what kind of insane crimp you may try.
If you put in the bbl, slide still dismouted and pry a case forward. You will never get anywhere near the extractor
with the front of the rim, with a loaded round in the chamber and bbl locked in place. I have checked this on
four or five 1911s, then got bored and stopped bothering. A few had as tight as about .025, but some seemed (without
the feeler gauges) to be closer to .060.

This is just an old gun writer's tale, oft repeated, rarely checked out, it would seem.

The good news is that a 1911 firing pin will literally come more than 1/2" out of the breech face, so no matter
WHERE that case is, the FP will find it.

1911s headspace on the case mouth, just like all other rimless semiautos.

Yes, 358156 - this is why I always say, "taper crimp as a separate step".

If all else fails try to get "Hallock's .45 Auto Handbook" copyright 1980 published by The Mihan Co. It has a very good section on the magazine and release point adjustments for wad cutters. I have seen magazines that would cycle fired cases without an issure when hand cycled. The release point could be part of the problem if comments given above do not resolve the issue.

Sept. 10, 2021 Steve left us. You are missed.
The above comments fixed my problem, haven't had a failure to feed since. Love the gun.

Ken Hallock's little book taught me a whole lot about 1911s, and I have talked to the man
himself at gun shows many times, very nice gentleman. He missed for a few years, then
made it back and when I commented, Ken said that his health had been poor, was happy
to be able to make it to the gun show again. I haven't seen him since, probably 5 or 7
years, hope he is still with us. He knows a lot about 1911s, old school style, and his book is
well woth having.
