    Question about 3" Kimbers

    I've owned a few K guns in the past, but just picked up a Super Carry UIlra+ .45acp. Feels great, shoots very well, but occasionally I get a hung up ball round stuck against the hood. With other 1911's over the years, I've polished the hood with a cotton wheel and a bit of Simichrome or similar product and the FTF problem has gone away. Not with this new Kimber, though I admit that I've only put about 300 rounds through it. But since the problem is consistent with over a dozen good mags, and with half a dozen. brands of 230gr FMJ, I'm wonder if the extractor may be too tight? Also, it feeds Hornaday Critical Duty or Defense without a hitch.

    I have three other 1911's and they all eat anything I feed 'em. Any suggestions with the 3" Kimber?

    What brand magazines do you use. I have an ultra carry. I have feeding problems with anything except Kimber magazines.

    Another thing to look at is the recoil spring. They only last 300-500 rounds. Try replacing that.

    I've used Colt, Wilson, McCormick, and even some after market Mecgars. Since I posted the thread, the problem is becoming less and less frequent so it may have just been a break in issue. Plus I did polish the hood again. I really like this shortie!

    I find 3" 1911s to be very finicky. I had them before Defender Kimber and Metro Arms and they all exhibited the same issues as you described. I traded them all. Now all I have as small as 3.5" bbl Colt Officers ACP then up to 4.25 Commanders and FS 1911s.

    As with all 1911s grease or oil in the frame and slide rails, I have a Colt defender with 0 issues and the Kimber's Ultras are good guns also.

    As I recall, Kimber wants oil on the frame and slide rails, not grease.

    Short 1911s have to get everything done (feed, fire, extract, eject, then feed again) in less time (due to the shorter distance the slide has to travel) than the larger models. Because of that, everything must be spot on; extractor tension and profile, ejector nose profile, recoil and magazine springs strength, and slide stop inner lug profile.

    Every Kimber I ever owned came with the extractor tension set too heavy. Your recoil assembly may also need to be replaced (I think the spring life on those is around 500-700 rounds).

    Once everything is set up properly, the little guys can be made to run reliably.

    I have one that is accurate, and has been totally reliable for many years now. That said, it took a good bit of work to make it so.

    I bought and broke in a Kimber Micro 9; it requires detailed cleaning before being shot; it likes 124 grain ammo, it requires that it be shot wet-ie., oil the slide grooves; it requires to be sling loaded on the first round; and it required 500 rounds to get broke in... ...it now shoots well and is very reliable...

    The Micro 9 isn't a 1911. What works for the Micro 9 may or may not work for a 1911.

    The Micro 9 is a slightly enlarged Colt Mustang.

    Exactly right!
