Lots of complaints about MIM parts around here.
So far, I've not had any MIM parts break. I did have a "quality" extractor in a Series 70 Colt break, but this was after many many many thousands of rounds in a gun I used to shoot IPSC with.
Statistically most parts fail early in the product life cycle -- so called infant mortality which is why manufacturers offer a warrenty to keep the customer reasonably happy, or very late in the life cycle -- wear out phase. This is called the "bathtub" failure cure in textbooks.
My failure in a machined metal part would probably be considered to be in the wear out phase or one of the low probablity random failures in the normal lifetime phase -- I though needing minor parts replacement after 10000 rounds was "normal" for a miltary contract 1911.
My question is how many have actually experience MIM parts breakage and if so was it low round count say less than 500-1000 rounds high round count >10000 or "random" after solid break in, but well before normal service life?
