What is MIM parts?
Are they strictly aluminum?
But,what about steel parts? The block of steel was cast wasn't it?
How do you identify MIM parts?
If I swap out the MIM parts;
How much will it change the guns weight?
How will it change the guns performance?
Wll the gun recoil slower,heavier?
Will accuracy be affected?

    METAL INJECTION MOLDING.

    ""The molding process allows complex parts to be shaped in a single operation and in high volume. End products are commonly component items used in various industries and applications. The nature of MIM feed stock flow is defined by a physics called rheology. {the branch of physics that deals with the deformation and flow of matter, especially the non-Newtonian flow of liquids and the plastic flow of solids.}""

    Like any manufacturing process, it can be good or bad.

    Colt uses MIM sears in the 1911"s , does anybody think colt 1911's are second rate??
    Raven guns uses MIM parts too, are those 1st rate guns??

    "No" or "nothing" to your questions.

    MIM stands for "metal injection molding". Powdered metal is combined with a binder in a mold; it can be done with many metals, but all the MIM gun parts I am familiar with are steel. MIM can only be done with small parts. Your car's engine block will be cast, whether using steel or aluminum.

    If you don't like MIM gun parts, you can swap them out, if you can find forged replacements. Some companies have better quality MIM parts than others; they are not inherently "bad". I'm fine with a S&W with MIM parts, but would be inclined to swap out parts on a Taurus or Kimber2.

    Steel parts will be very close in weight, whether MIM or forged. You won't notice a difference. The accuracy of your guns will continue to be determined by operator error.

    According to what I have read, the process has to be near perfect or parts are sub-standard. Glock, Colt, S&W and others use them. Those found wanting are Kimber, and I would say any other company not known for high quality firearms.

    I know connecting rods ( cars ) are made this way as many other parts and do well ,
    It was explained to us there just as strong and require very little machining so it saves time and money about 10 years or so ? ago They also explained its the way of the future that machining parts will become a thing of the past on a lot of items .

    One other thing I forgot to address. MIM parts. A company that I will not name gave the MIM parts a bad name because they had a bad batch of MIM parts. This was many years ago. Since then remarkable things have happened.

    MIM parts are extremely dense and very exact. They are much less prone to wear and breakage than a factory Colt, Spfg. etc. part. This is why we use them in our CQB's, etc. Although not quite as hard as our tool steel parts, they will last a very long time. This is why we can still quarante our total gun, including the MIM parts, for life.

    The tool steel parts are actually overkill. The MIM parts last for life (I know of one gun that has over 100,000 rounds thru it and the trigger pull feels the same as it did when new) therefore I guess you could say the tool steel parts lasts for a lifetime and ?.

    We use the tool steel parts in our full custom guns. (These are the ones that cost from $2800.00 up) Our full custom guns, Stealth, Tactical Elite, Super Grade and Tactical Super Grade, are not for everyone because of price. They are intended for someone that can afford the very best we can do.

    They [tool steel] actually won't last any longer, shoot any straighter or be more dependable than our CQB's, Protectors and Classics, but we spend many extra hours in fitting and prepping them for a perfect cosmetic handgun as well as a great shooter. And because of this, we use the tool steel parts that take longer to fit.

    Again, all of us guys here, including Bill Wilson use the very same MIM parts in our guns. And we shoot a bunch! Once installed and fit, no one can tell the difference in the feel of the trigger pull with either type of parts.

    Ok, I'm done with my book. Hope this helps too. Just didn't want you all to believe everything you read from self appointed experts.
