Well I note that there is much MIM on the new Champ. But it shoots like a dream, nevertheless.
So I have been pondering the MIM issue again. Is MIM really a problem?
It does not really seem so. Sure, I would probably feel better if all MIM was replaced. But as long as she functions well, does it matter?

On another note. I noticed that on the new Champ that when I drop the bbl in the slide the lugs mate with the slide about as perfect and tight as possible. No play at all. It is a bull bbl and very accurate.

On the other hand the other day when I was cleaning my older TRP I noticed that there is some play in this same area. However, the TRP is amazingly accurate. So how much of an issue is the play in the TRP. Seems like not at all.

Any opinions or comments on the MIM and the difference in the fitting of the barrels?

MIM has been beat to death several times. Yet there are few first hand reports of MIM parts failing.

Personally I see way too much commotion over this thing. I have a Loaded model and am happy, it is very relaiable. Hey if the gun runs, what's the problem? same for the full length guide rods everyone hates, big deal, run what u brung.

Sticky: Forged? Cast? MIM? Stamped?


Check out the site's "How To" and "FAQ" section. There's a ton of info to be found there. It's a good place to start reading here on the forum. I found it to be a tremendous help to me when I started browsing here several months ago.

I think you've answered your own questions....

If they all run and accurate, NO WORRIES.:rock:

MIM and barrel lockup.

I'm no gunsmith, but I've been using the platform for two decades and learned a thing or two.

If MIM parts are going to fail, they will usually fail right out of the gate. If you've gotten through a couple boxes of ammo, your MIM parts are fine. If it bothers you, they can be replaced. If it doesn't, leave them alone.

Whether or not the barrel is "tight" in the lugs is irrelevant. What matters is that it locks up consistently. A good bushing to slide and barrel to bushing fit, along with the lugs and barrel hood/breechface locking up the same way every time makes accuracy. Tight or loose doesn't matter, consistency is the name of the game.
