    :dunno: Is it just what some of you say to justify paying over a grand for a pistol?

    From the little bit of reading I've done about it I think its related to perhaps earlier days of MIM parts that were made without alot of care or experience. I'm led to believe that you can make good strong mim parts or cheap weak ones. Much like forged parts really.

    MIM parts can have voids in them from trapped gasses. Sometimes the bubble is on the edge and then it's obviously defective and those parts are melted down again to be re-molded. Sometimes a void is hidden inside of a part; if the parts aren't inspected with ultrasound or x-ray or something, then they can get into circulation and later break.

    It's an occasional side-effect of squirting a liquid into a mold. :dunno:

    There is nothing intrinsically wrong with MIM.

    Just like stamping, casting, other forms of powder metallurgy, etc., it is just another tool in the designer's shed. Properly implemented, it can provide adequate performance while saving a lot of money. Improperly implemented it can wreak havoc. Just like any other process.

    That being said... there are some poorly thought out MIM parts in the gun world :( Just don't take it to mean that all MIM parts are bad.
