    I have a new 686-6 that I purchased (yeah i know should have bought an older one blah blah, there's something special about the gun only ever being yours ie. new) and I was wondering if you could replace at least the trigger with a non-mim part from an older 686. I know the hammer would be a no because of the design.

    Don't listen to all the internet babble, MIM is not a big deal, your trigger will be just fine.

    ^^^...this. Your gun is warranted for life. MIM parts show no more of a failure rate than non-MIM parts. Have the trigger slicked up a little maybe if your are too impatient to slick it up yourself by shooting/dryfiring, but why waste money needlessly?

    My 696 has a MIM trigger, and I am unconcerned. The action is real nice in SA & DA. I like it a great deal. But hey, it's yours, so do what you wish. I do not know if the older triggers will swap out. Good luck.

    There is not a thing needing replacement on your 686-6 revolver, not a thing!

    That's kind of what I thought, thanks guys!

    I love this pistol ALOT. So much so that I may be buying another (4") by the weekends end haha. Although a 6" 586 would make a col brother for it.

    Enjoy your Smith. Tune it to be yours. Yeah MIM can pull at your heart. But guess what! MIM wil take to the stones and springs well. And I don't care what folks say. You can not make a Ruger trigger into a simple Smith without spending more than it's worth. Nor can you make a Smith or Ruger lock up like a Colt. There is always a price to be paid.

    A GP100 or 6 will give you a good trigger over all and solid forcing cone to face. A Smith will over all give you a better trigger out of the box. And choose your X86 right and you could get a fantastic cylinder face to cone machine and a crane to die for. But the lock up wont be so called Colt lock up. Get the Colt and if it's right you have the bank vault lock up and a match rod lock up. Something else even a new Smith will give you if right is near match if not match grade lock up. A proper set up colt will give you match grade rod. I've never seen a GP100 out of the case take a match rod. And yes when I have cash in pocket,,, I have my rods in a pocket also. :)

    The 686 is a fine weapon. I kick myself for getting rid of my 6" about 20 years ago. That was a really good, accurate-shooting gun!

    I don't know that I'd change the trigger either, as it's a bridge I haven't come to.

    But the question was, can you change the trigger?

    The answer is, "yes you can, provided you switch a complete trigger assembly, including the hand - along with the rebound slide and spring. Should anyone go in this direction, be aware that K and L frame revolvers use the same trigger, but different hammers.

    The funny thing is, everyone hates the MIM parts on S&W revolvers but Ruger is basically a gun entirely made of MIM parts, frame and all. Metal Injection molding is very close to Investment Casting used by Ruger to manufacture their whole gun. (to my way of thinking anyway)
  13. Old Fuff

    Old Fuff Well-Known Member

    No, the two processes are entirely different. In the case of Ruger's investment castings the steel is melted and then poured into a mold. The resulting part is 100% steel. An MIM (metal injected molded) part is made up of metal partials that are fused together. The particles however are never melted, and the part is never 100% of the base material. Close, but somewhere in the upper 90% range.

    Nope.... At least on my part.

    I can, and do, live with MIM lockwork in several Taurus revolvers, but if given the option I would prefer 100% steel lockwork. With it I know exactly what to expect because it has a long history. MIM parts have yet to do this, and I worry about knife edges and corners breaking down over time.

    You can make extreme modifications on steel parts that can be welded, but don't try it on anything made using MIM technology. Of course very few people do things like that.

    The supposed advantage of CNC machined parts and MIM lockwork is that tolerances can be held so close that a trained monkey can put guns together, and therefore eliminate the need for highly skilled (and expensive) final assemblers. Apparently it has also reduced the need for frequent inspections as well. From the manufacturer's point of view all of this relates to important cost savings. I can see and understand where they are coming from, but forgive the poor Ol' Fuff for thinking all of this necessarily results in a better product. :uhoh:

    How many times do I have to admonish you!!!

    Let them buy the crap so that we can acquire the good stuff!!!

    We need LESS competition for the diminishing resource...not more!!!

    Quit clouding the issue with facts!!!

    Old Fluff...Can you replace the hammer as well and all the other MIM parts too?
  18. Old Fuff

    Old Fuff Well-Known Member

    I know, but I can't help myself. Once a blabbermouth, always a blabbermouth.

    But on the other hand MIM parts are becoming so mainstream that I doubt anybody pays any attention to my confused rants... :confused:

    It isn't that MIM parts won't work, as much as concern about how long they will, and that's something only time will tell. By the time the answers are known for sure I won't likely be around to care. However I always have the option of betting on a well-proven sure thing. ;)

    I haven't tried, but I don't think so. With the exception of hammers made for rimfire revolvers the older hammers have hammer mounted firing pins, and are higher at the top. Hammers made for the J-Frame "inclosed hammer" models might work if the internal lock was removed, but not otherwise.

    A complete exchange of all the internal lockwork would get expensive, so I'd expect it would be more cost effective to buy an older revolver in the first place.

    Unfortunately there is no such thing as a free lunch. :(

    Of course not...in some ways they are better.

    And in many ways they are not.
