I have owned my Kimber Custom II for over a year and about 1300 rounds. I have had no problems with MIM. Also, I have a Rock Island with MIM, no problems.
All this has led me to the conclusion that if an MIM part is going to fail, it'll do so early on.
Just FWIW, I have seen both Colt and S&W revolver hammers broken off, and that was decades before MIM was even dreamed of.
How much is "A Lot"? I paid $630 NIB for my Custom II,
I have to assume that the MIM extractors varied in quality, or inconsistent, since mine works great
If Kimber had a 1% failure rate of mim parts, 1% of 60,000 pistols is 600 broken parts.
"unlucky 600"
I would love to see old time hand fitting and gunsmithing techniques apply to every American made firearm produced today.
