Had a couple of FTF/FTE on new/used TM. Gunsmith did a recoil spring, extractor, strip and clean. He said internals are all tool steel, which seems to be favored over MIM. He shot a magazine at 25 feet offhand, said it made a one hole group smaller than a quarter. Grip safety seems to have some play, but he says that's a non issue regarding function. Very happy with this 1911, the first I've owned that I like.
