    I took my piece to the range yesterday and put about 220 rounds thru it. I had 4 jams: 1 FTRTB, 2 Stovepipes, and 1 funky one where the slide locked and a live round was sitting (loose) on top of the magazine. I figure that last problem was the magazine, it's a Chip McKormick 10 rounder. I kept a closer eye on things this time around and I don't believe it's any kind of a stem-bind. The FRTRB occured as the rim was starting to slide under the extractor...and judging that I had 2 stovepipes I'm thinking this may be an extractor issue. The gun did seem to function more reliably this time around. At this point I've put about 550 rounds thru it since new.

    What are your thoughts on the matter?

    The 1911 can be a great gun but it can also be very finicky. The best thing IMO, is to limit weak points and increase your chances of reliability.
    That said, I try to find ammo my guns prefer (accuracy, dependability, reliability & clean) and I use only Wilson mags in my 1911s and so far, my 1911s have been very reliable.
    Lastly, not having seen the malfs, it's tough to say.... ;)

    I use that same McCormick mag in my Kimber, Not many rounds through the mag but no failures so far.

    Exactly what kind of failure is a FTRTB?

    Your FTRTB sounds like a problem with where the round is releasing too early or too late due to magazine lip and/or follower design. The stovepies may be an extractor issue, or possibly even an ejector issue. I'd PM 1911 Tuner and see what he has to say. For more on the mag lips/follower issue do an advanced search for "magazine observations" limit it to posts by 1911 Tuner in the gunsmithing sub forum. You should be able to find his thread of that title where he discusses the magazine design and how it affects operation in the 1911 with it's controlled round feed extractor design. Old Fuff and others add more insightful commentary and the thread really helps one to understand how a 1911 should be feeding when operating properly - and that includes the mags.
