Just my observations paralleling what happened with S&W vs. what may happen with Ruger, since I also buy S&W's and watched this whole MIM thing unfold (blow up?
) in the late 90's- early 2000's with Smith......
I don't think Ruger will be quite as affected by the MIM as S&W was, mainly because Ruger hasn't been around as long and the designs are more modern. More Ruger fans will tolerate a MIM part SP101 than S&W fans have tolerated MIM Model 10's and 64's........the main argument is "after over 150 years of forged parts they started using MIM!!!"
Another big complaint of some S&W guys, is that "the firing pin belongs on the hammer!!" and they won't buy "some MIM gun with a frame mounted firing pin" obviously a frame mounted firing pin doesn't bother us
Also, I believe more Ruger fans like us are shooters, as well as collectors, while S&W has a LOT more guys who consider themselves only "collectors", and they feel once MIM came along there was nothing worth collecting and it drove the pre-MIM guns prices up.
S&W fans were aghast in the late 90's when guns like the Model 10, 586, etc. appeared with MIM parts and it caused a huge uproar. I honestly think the Internal Lock caused much, mouch more acrimony than any MIM ever did. Even some of the most die hard S&W "boycotters" say they own S&W's with MIM like pre-lock 686's, but they won't buy one with a lock.
Bottom line, I think we'll all survive, and no one will turn to dust or a pillar of salt for touching a GP100 with a MIM trigger
The guns will still last 5 lifetimes, they will just look a little different.
