According to post on this forum Tisas is doing away with MIM parts in their 1911s (not sure about other models). How will you know if you have one with or without MIM parts? Are they going to start putting this on a hang tag the way they tell you about their forged barrels and slides? I have a...

MIM seems to work best on small, (short length) low stress parts. You will note that Colt only uses MIM on four small parts - the mag catch and lock, disconnector and sear - and has a nearly 0 % failure rate - on these parts. How much of this is the size and geometry of the part vs. a well done MIM process is hard to say.

I understand the concern about MIM parts. Over the past couple decades, I've owned various manufacturer's guns with MIM parts. No MIM part ever caused an issue...
