Pretty much any 1911 does it due to the angle at which the round is fed into the chamber. Load a round by running the slide home slowly by hand to see what I mean.
Just be glad your gun isn't a .40 S&W! That caliber has major problems with setback in just about every brand of ammo, and it's a bigger problem because .40 is already a high-pressure round.
Also a problem for old Glocks, the ones without a fully supported chamber.
In my experience it's not really a problem with a .45 1911. My advice: try to only let it happen to one or two rounds, as it seems to me that the shorter OAL of deeply setback rounds can cause feeding issues. After awhile, shoot the top round (or throw it out if you're worried) and move on to another.
1911s are traditionally proofed with a double-pressure round, so they can handle more pressure than the standard cartridge is designed to deliver. Personally, I have fired every set-back round I've "created", and never had a problem.
In .45, that is. I throw away .40s that are set-back.
