I've posted this before, but I have an M1A that broke the MIM hammer in under 100 rounds fired. SA replaced it with a forged part. My son has a Taurus PT1911 which broke the MIM slide stop right in half. We replaced it with the "defective" MIM part that came out of my Kimber UCII when I first bought it and which the factory had replaced, and the Taurus has been soldiering on with the MIM Kimber part for over a year now.ChuckW wrote:Agreed! This thing about Kimber and MIM parts keeps being raised. Folks will have stories that they have "heard" that some friends uncles 2nd cousin had a MIM part on a Kimber that broke. I am a member of a 1911 forum that gets a high number of posts related to Kimber, and other 1911s, and I have yet to see a first person account of a MIM part on a Kimber actually breaking.7075-T7 wrote:They might use MIM parts (though I don't see what the issue is with quality MIM partsrm9792 wrote: Kimber does have MIM parts and they are a gamble with relation to breakage. .) But their aluminum frames are milled from billet aluminum, not forged or cast, making them the strongest and closeset to design specifications possible. IMHO
Go figure.
But my point is that I don't know that MIM is a problem per se as long as the manufacturer is making high quality MIM parts and not junk.
