I should add that a lot of 1911 problems can be traced to magazines. Not "bad" magazines, just magazines that don't run well in a particular gun. They might in another. I've found Springfield Armory factory magazines seem to run all of my 1911's the best. It least they seem to give the fewest problems overall. Wilson Combat runs my Colts the best.
I think with most 1911's, once you get the magazine situation sorted out, (and on some guns that can take some doing), you're pretty much good to go. That is assuming you're feeding it the ammo it likes.
This is a true statement. Mags and proper ammo. Gun was designed around a 230 ball round and that i what they like. A little love and they will run hollow points. Speers with the "HUGE" mouth will give most any 1911 problems. A bit of work and they will eat them to.
I have found that Wilson 48-D and Chip McCormack Power mags (10) rd. run in all of my 1911's
I do not even take the factory mags out of the case when I put a new gun in the safe. Ammo cans full of loaded mags at the ready.
