MIM Parts not durable? - Page 2 - XDTalk Forums

**Cannibul** · 10-11-2009, 09:50 AM

The only parts on a 1911 that I have ever had break have been Colt parts. And those are not MIM.

Cracked a barrel bushing on an Officer's Model. But that shouldn't count as that happens quite a bit.

I've also had two slide stops break. One on the above mentioned Officer's Model and one on a Series 70.

hmm isn't there a test or study done with MIMed gun parts to see how long they'll last compared to Forged parts, in real life? I understand how MIM parts are perceived to be less durable when you read it on paper.

wonder if there's such a thing.

I haven't seen a study of MIM vs. forged or cast. I do know that some guns use cheap MIM processes and cheap metal and then they break such as early Taurus 1911s. Others, like Kimber and SA seem to have the process figured out now and have very few issues and their guns are very reliable.

I was dead set on changing out all of the MIM parts in my Kimber, but with about 1k through it I have had no issues to date.

If you buy Dan Wesson 1911s in the same price range as Colt,Para,SA,etc.
you will get no mim parts..Thats what they tell us anyway..
I'll tell you the CBOB I just bought is the tightest,most accurate,balanced,
beautiful 1911 I've ever had...

My Para 14:45 has many thousands of cast lead reloaded rounds through it and the only thing that ever broke was the barrel bushing..(not mim)
I wouldn't worry about it but think more about who put all the pieces together..

Once again: my 2 cents, and worth what you paid for it..

MIM that survives a break in period of several hundred to a few thousand rounds is usually good to go, and can be expected to have a long service life. The problem with MIM is not so much that it can't be made strong and free of voids, it's just that you can't tell when it isn't, until it breaks, which, again, is usually early on.

My Para Ord LDA CCW however was the example of poor quality MIM, The slide stop bent, x-tractor broke, magazine release broke all in the first 1500 rds.

wow, he said the exact same thing you did and you get on him like that, wow. I know you don't like some people,but that shouldn't color a factual discussion.

As he implied, if it breaks it will break fast, or in essence what others have said usually if it survives the break in period you can be confident it will survive, you CANNOT be confident before that.

If you can buy a 1911 with better fit and finnish with no mim for the same price as the others why wouldn't you?

**Frenchy** · 10-29-2009, 08:33 AM

No problem with MIM in the Smith revolvers I've owned.

Sorry I did not mean to come across that strong.

With the vast numbers of Springfield, Kimber and other pistols with MIM parts out there...if it was iffy...they'd get rid of these parts by now. However, this is not the case.

You do know that not only 1911s have MIM parts, but many mid to high range rifles and shotguns have a few MIM'ed parts as well...right?

Again, I would not sweat it. If it bothers you THAT much...then buy an older 1911 Colt that did not have any MIM parts. After years and boxes upon boxes of rounds through a Springer and Kimber than have many MIM parts...I have never seen any troubles.

You are also aware that machined parts on Colts HAVE crapped out early too...right? It happens.
