Generally a Model 94 will last many lifetimes with "normal" use...but as a gunsmith I have seen a few come in with wornout hammers, they still work but the "safety notch" is worn to where it no longer will catch, and therefore is unsafe to use. Usually the owner brings it in AFTER an accidental discharge! Other than that...very few repairs. Also the '94 with the right ammo is more accurate than most people realize. I worked at a deer hunting rifle "sight-in" clinic for a few years here, and got to try out a large number of Winchesters benched at 100 yards with both open sites and scopes, all printed a good 2" group...pre or post 64 no matter with boring regularity. Almost all the problems people had with them were with the shooter, not the rifle. Mostly in the area of knowing the sight picture. My favorite? A very old '94 trapper with a 16" in 30-30...no finish left on it, but it still shoots like a dream.
