yep, they use it in all model's including the Professional.

pretty much everything except the slide, frame, springs, grips and barrel.

the MIM stuff is all hype.

people that hate MIM in gun's shouldn't be driving a car or flying in a plane.

Last I checked, not too many MIM heim joints on them stabilizers.

Still, I have lots of MIM in Kimbers and other guns (including a Springfield GI) and have no intention of trading it out. The stuff runs good.

I figure after a coupla thousand rounds, stuff should be good to go...

As has been pointed out elsewhere, bar stock parts break too.

I tend to check the parts when I clean (another good reason to clean your guns, especially if you depend on them) and replace anything worn or damaged.

 

I know you guys wouldnt swap out the mim parts but if you had to what would you say are the most important ones?

 

#1 Sear and Hammer, I think.

 

Slide stops what I tend to lose.

 

I don't have a huge beef with MIM parts if they're made correctly. Springfield seems to have the MIM process down better than anyone in the industry from what I've seen. I've not heard of many of their MIM parts breaking at any higher rate than that of parts made of old fashioned steel.

There are a couple companies out there in the 1911 business using MIM parts who I would not trust at all. I've heard too many stories about their parts breaking. I'll not name names so we don't start a flame war.

In this day and age MIM...it's the norm so I accept it. If done correctly, odds are, you'll never have an issue with a MIM part any more so than something made out of old fashioned steel. I do like parts made out of steel better..but that's probably me just being old fashioned. MIM parts have not stopped me from buying several Springers over the last couple years. They're just made well and I don't care about the MIM parts with Springfield. If they bother me enough though...I just swap them out for steel parts and call it a day.

The MIM thing in most cases is a bit overblown...it's really about the quality of the MIM parts and your own preference in the end. Steel breaks too...I've seen it happen with high end Nighthawks...so nothing is perfect.

 

If you asked this question so you could avoid 1911s with MIM parts, then you may want to check out Dan Wesson 1911s - the valor and the heritage. From browsing the DW forum, I think both of those pistols are MIM free. I have no experience with either pistol, but that forum should clue you in if you are after a MIM free gun.

 

Other than a boatload of hype and paranoia, there really isn't any reason to be concerned about MIM parts.

 

For me, having been shooting the 1911 for 40 years, I prefer all forged parts, NOT because I am biased against MIM, but mainly because I average 1500 plus a month rounds at the range. That said, I took, several months ago, a newly purchased Springfield GI, and put MIM in all the parts that were not MIM, and I've been using that pistol as an MIM test bed, and I can say now, that as of today, it has now fired a grand total of 8,672 rounds without one single issue, and I will continue until a part breaks.
