Is this why Kimber has such a doo doo reputation these days? Do you recall what your round counts were, approximately, when the failures occurred? Thanks for sharing your experiences.I have had two MIM parts fail on a Kimber Ultra Carry II years ago - an extractor and an ejector. That's it. If MIM parts are done correctly, to the right stress specs, they are good parts that need a very small amount of fitting, but if they are not done right, they are junk. 10 or 15 years ago several manufacturers had problems with them, but these days most of them are fine. Having said that, I still prefer bar stock steel parts that are properly fitted because of my experience. That was one Kimber out of eight that I had, and several that my best friend had. I still have three of them and they are still going strong.
About 3000 rounds of 230 gr. and some of them were +p (which aren't supposed to be used frequently in an alloy frame gun).Is this why Kimber has such a doo doo reputation these days?

I will rest well tonight knowing my beloved TRP pistols are still gucci. Thank you sir.MIM is of the devil, indeed, or so we keep hearing. And that boogeyman lives in the heads of many a tacti-tube-video-operator! I have yet to lose a MIM part in any pistol, and some have been in match use for years - a TRP included.
Just like ammo improves, and polymers improve, and manufacturing in general improves, so does MIM. No reason to expect that MIM would be relegated to remain what it was decades ago.
In their defense plastic containers reduce testosterone levels in men. Though it appears that wouldn't bother you, so fair play. Also, now that you mention jet engines have MIM parts i am definitely not flying again, though I was 99% of the onboard with that idea already.Colts have MIM parts, jet engines have MIM parts. LAPD SWAT teams put Kimbers with MIM parts thru 5,000 round torture tests..nothing failed.. The same people probably didn't like it when they started putting milk in plastic jugs...
That is an interesting point. Do you think that Kimber and SA are still machining on their clapped out equipment? I do not really go into gun stores and padiddle guns like some people do, so I have no idea what theyre pumping out. My TRP Operator is very tight, smooth slide, complete silence if you give it the honey badger shake.Kimber and SA are not great guns but NOT due to their MIM parts but due to their old worn machines and lack of tolerances (Kimber) and SA due to rough machining and entire lack of fitting. Colt...we don't even go there, a joker gun still...what are you doing Dan Wesson and when?
I have a bunch of SIGs, 226, 220, 320, 365, oh 210, those are FULL of MIM parts. The 220 SSE 45 ACP and the 226 SSE are the 2 I would grab when the zombies (or other) are coming for me. Never a FTF, any type of malfunction or anything else. The SIG parts on the P-series like hammer, sear etc are very finely finished, no mold lines, no ejector pin print marks and you'd never know they are made by Indomim in India. The 210 is Mim everywhere plus chem machined for slide frame fit and still a work of art when it comes to modern fabrication too good better than the old version to me anyway. So it's not about MIM parts, it is about the willingness to build a perfect gun. Kimber, Colt and The Springfield Armory are a few steps down from that, a few too many.
Welcome back! You didn't miss much, other than sharing in the foreboding general sense of consternationI’ve been away from the Forum for more than a year, but I see that some discussion subjects never change.
But to partially respond to the good, fair question, there have been countless photos of broken MIM 1911 parts. Almost always, these are the parts that are the most stressed, given the 1911s design. Of course, non-MIM parts have also broken. That’s a regular counter-argument. As to myself, I’ve never purchased a 1911 with MIM parts. So my lack of MIM breakage doesn’t mean anything with regard to 1911s. But I have had no issues with a gun that’s designed from the outset with MIM parts, sized with sufficient mass to assure reliability. So no negative sentiments or negative personal experiences with MIM. But I still prefer to use/accept MIM only in parts that are less stressed and/or that are sized in a gun’s original design for MIM fabrication. Just me…not preaching to anyone else. MIM has a place, but people do have different perceptions.
Seriously? If you're here, you have access to the internet, no? If you really want to believe there's a modern firearms manufacturer in this country (or most others) churning out guns machined on "clapped out" equipment, you're simply not keeping up with industry news.Do you think that Kimber and SA are still machining on their clapped out equipment?
