good question, one thing i can say is that MIM parts have come a long long way in the past few years.
i just got a bag of MIM colt and a couple PI made parts from numrich the other day.
they don't look at all like the pore-filled ,pock marked and grainy parts of the past.
there slick and smooth and feel very dense.
i don't think there are going to be any problems with these.
i have no problem running a safety, grip safety, mainspring housing and the like MIM.
a sear or dissconnector -- i have to think twice about ---
