My SRH in .44 mag has a MIM trigger. Should I be concerned about it?

Most of the lockworks in your gun are MIM parts. Should you be concerned. IMO Nope! Ruger makes them just about as good as they can be made. Nothing wrong with MIM parts this day and age! George

I've yet to have any problem with mine, but some gunsmiths will not do action work on a gun that has MIM unless non MIM parts can be found and substituted.
There is a reason that the old pre-lock and pre MIM Smith and Wesson's are going through the roof in price.

yep, goes back to when they started making things out of aluminum, and plastics, polymers, and NOW "MIM",,,,,,,,,,, wow 8)

S&W's early MIMs were oogly (still are) and not fully equal to forged parts in terms of hardness and porosity.
I use those terms broadly & will not argue or defend them with people who want to nitpick the terminology to death.
Many gunsmiths (including one I talked to inside S&W's Performance Center) did not & still don't think they were "as good as" a forged part.
Again- I will not argue this, I'm just laying a foundation.
Ruger doesn't do their MIMs the same way.
They contract MIMs out, use a much-advanced generation of MIM material over the early S&W formulation, and they do more final machining.
The material is different, the parts look much better, MIM is used where it makes sense & not used where Ruger feels it'd look cosmetically challenged (hammers in GPs & Reds, for instance).
I wouldn't be concerned.

If you're worried about MIM parts, then worry about all the cast and MIM parts in that car that you drive at 70 mph just a few feet from other cars doing the same.
I wouldn't give MIM parts in a firearm a second thought.

They use MIM parts because it's cheaper, not because it's better.
Oh BTW.....how are you guys liking those fly-away SR1911 sights?...
Just sayin'.

I didn't hear anyone say that MIM parts are better! I didn't say that. What do you think a LC9 or a Glock or a M&P .45 cost to make. Stamped steel and MIM parts with Polymer plastic, Not much I'll tell ya!.Ya it's all about cost for all makers other then custom gunsmith work then your pocket is key to the best gun you can get. Ruger makes one heck of a S/A gun for the money. IMO it's one of the best for the money that is.. George
I hate to seem stupid but what does MIM stand for?

That happened to me. Not a big fan of MIM parts myself.DGW1949 said:

MIM parts have been used extensively in aircraft, including in jet engines, for a couple of decades. Obviously, they are no good. Plus, the moon landings were faked, and the earth is flat. :roll:
Show of hands: Who would prefer MIM parts on their guns as opposed to standard steel? Didn't think so :mrgreen:
Clark: Yes
Cholo: No
Next?

IMO, functionally there isn't a thing wrong with MIM parts. My main issues with them, if at all, is cosmetics. I didn't care for the odd shaped hammers on the sp101 or GP100 revolvers, and this is a small thing, but I wish the color of the MIM trigger on the GP100 more matched that of the frame. However, in all honesty, if the triggers on the GP100 revolvers had been that way since day one, I wouldn't even think about it. It's quite common on other revolvers for the steel color of the triggers and hammers to be different than that of the frame. Sorry, just rambling, MIM is ok! :)

Maybe ask the question another way; who would prefer to pay 50% more for the same gun to keep the forged parts.
50%, huh? Wow, that's a lot! :mrgreen: Can I safely add you to the "yes" column in that you prefer MIM parts to traditional steel? I doubt it would cost 50% more for a steel trigger, and other small parts.22/45 Fan said:

It seems to me that most of the MIM-phobia comes from those who never took a class in materials engineering - yet are suspect of professional ordnance engineers?
Puh-lease! Go to a library and ask for the ASME and ASTM reference series sections.

It's a little ironic for this discussion to be on the Ruger forum. I am old enough to remember the years when many decried anything Ruger as cheap, cast-metal junk!

Well made investment Cast is way different then MIM parts. A lot of your top brand guns are investment cast and there is nothing wrong with that, and most with some MIM parts in them. Ruger has build and still builds a darn good and strong fine shooting firearm. Name a few brands that build a S/A revolvers better then Ruger for the same price point. Metal Injection Molded parts today are darn good if there built right. The zinc cast guns were the junk of my younger days. George

Two questions:
1) When MIM parts replace investment cast, forged, or tool steel parts, does the price of the gun go DOWN?
2) Where are the MIM magnum revolver cylinders and frames, and where are the MIM high power rifle bolts and receivers?

I know all this, George. But back then, investment casting for guns was new, and Ruger a pioneer. "Everyone" "knew" forged parts were better, and Rugers were lambasted as junk by the snobs and the ignorant.

pisgah, Yes I see what your saying now. Your right! It did take time and a lot of Investment casting to get better and better and even longer for people to get use to it. A lot of places that cast things used all kinds of metal to cast with in a lot of way gave it a bad rap too. But yes I see what your saying. About the only thing people like that was cast was stoves.
