    Which internal parts on a current SIG 1911 TACOPS are forged? Bar stock? Mim?
    I know the frame and slide are forged. I initially heard that many of the internal parts were EGW which is good.

    They are all MIM they used to be EGW but that is no longer the case.

    I have been told otherwise. I was told only four MIM parts are in the Sig TacOps.

    The Springfield TRP, on the other hand, has mostly MIM.

    Dave from Evolution armory has explained it a few times that they are all MIM besides the frame and slide they are made by Indo MIM in India. He worked at sig building them he would know better then anyone else I would imagine. Not saying they are junk just saying what I have been told.

    Honestly you should never get mim parts in any gun north of $1200 that is frigging ridiculous.

    Please correct me if I'm wrong, but I believe one of the only production guns that is currently not using MIM is Dan Wesson.

    A post I read from Keith in Jan. 2016 said, "There are absolutely no MIM parts in any, current, DW 1911's." AFIAK, that has not changed.

    I heard what the disgruntled former employee said. I also heard differently from a source inside the company. I will leave it that.

    Colts are suppose to have only 4 MIM parts.
    As far as 1911s go, my preference is forged parts, however, I have never heard of any issues/failures with Springfield's MIM components or Colt's, and don't worry about them.
    My only Sig 1911 had a cracked slide from the factory, to Sig's credit they replaced the entire gun, but I haven't bought any more of them.

    I would not want a MIM barrel, but I really have no problem with a MIM grip safety. MIM is better than plastic like one big manufacturer is using in some of its 1911 MSH's.

    And as WC pointed out, MIM failures in 1911's are extremely rare. Heck, a forged part can have imperfections and fail.

    At one point this subject come up in another forum, and a fellow shared a video from one of the Wilson family members, who said min parts will last a lifetime, and tool steel, and or forged parts will last generations. So unless you intend on living more than one lifetime and owning the same firearm then don't worry about it. But, having worked in castings in my life time, I do know there can be all kinds of issues with those kind of parts. Not necessary gun parts per say. But, I've seen castings come out too soft, too hard and brittle, loaded with air pockets and imperfections, cooled too fast etc... A number of factors play in to a quality casting.

    Kimber has plastic MSH on nearly every model they make including some of the very high priced models. 1st thing I change on every Kimber, then I change the internals. Wouldn't even own one except their bull barrels are exceptionally accurate.. and I love their Ultra's Have a Pro-Carry 9mm that's a good shooter as well.

    In all my years of shooting, I have only had one MIM part fail on me and that was from a Series I Kimber. Gave me an excuse to have my local 'smith go through it with a reliability update and replace all the other MIM parts.
