    I know some 1911s are chock full of MIM, and some have less MIM

    I'm curious which manufacture's 1911s are;

    full of MIM (all or nearly all)

    Some MIM (a mix of MIM and bar stock)

    No MIM parts


    I'm also curious to hear thoughts on where MIM seems to be perfectly suitable
    (like maybe the sear?)


    and if anyone has had a MIM part fail?
    anyone had a bar steel part fail?

    Thanks

    ..L.T.A.

    The only ones that I know for sure don't have any MIM is a Baer.

    I myself have seen a couple of slide stops and a couple of hammers break (Kimbers)

    The new dan wessons don't have mim, before this year the sti thumb safety was mim. I believe the sigs still don't, my 2 don't. Colt has a couple mim pieces. Wilson, nighthawk, baer, ed brown no mim. Sti, Kimber, springfield, ria, taurus, s&w mucho mim.

    Grip safeties are either cast or mim. I had bad luck with a chip mccormick grip safety but the sti mim gs seems to be good.

    Maybe its better if I do it this way. I would definitely not want a mm extractor, slide stop, bushing, guide rod, hammer, sear, fp stop. I'm not a fan of mim but the grip safety is not a high pressure part. The sti thumb safety is pretty good also. The mag catch I would prefer not mim.

    This is for carry, a range gun would not matter much. I like the option to carry everything though.

    Not sure about all, but you can request no MIM from Fusion.

    I have no issues with MIM as long as it comes from a quality source but I also prefer solid steel components when it comes to the extractor, hammer, and sear.

    I have had two parts fail on my 1911's and they were made from solid steel. The subject recently came up over on 10-8 and there was quite a bit of discussion about machined slide stops on Colts breaking.

    Your thumb and grip safeties are typically investment cast, even from the big boys.

    It's all about Quality Control.

    The only company that makes a semi-affordable 1911 with no MIM parts is Double Star. All of the big commercial names use MIM internals. The G gun uses MIM in their firing pins! (Lot of buzz in the LE world right now due to the nose of G _ _ _ _ firing pins breaking off resulting in a handgun that does not fire when you press the silly plastic tab that passes for a trigger.)
