I had a Colt back in the early 1990's that was 100% reliable with any type of ammo I feed it. Had a couple of springfield's that wouldn't run reliably on certain hollow points without some work. You have mentioned that 1911's have soul and character. That's part I the reason I don't like the MIM parts. I never had a problem with the parts but it just bothers me to have cheaply made parts on an otherwise quality handgun. So I usually change them all out.
