The ammo I carry will depend on which 1911 I'm using.
The 4" Springfield Champion does well with Speer Gold Dot 230gr +P, 230gr Hydrashok and 230gr Federal HST.
The 4" Colt Combat Commander seems to prefer 230gr Federal Hydrashok.
My S&W 1911Sc hates Speer Gold Dots of any kind, but runs fine on Federal HST 230gr (and the +P version). It also digests 230gr Hydrashok easily.
My Kimber Compact Royalle (officer's model size) performs beautifully on 200 grain +P and will eat the Hydrashoks too, though the 200gr seem more accurate.
This means that the carried magazine contains the ammo each gun likes best while spare magazines usually contain 230gr Hydrashok. The difference in accuracy isn't very significant as all of them will hold 8 shots into the black at 25 yards.
The Kimber poses the only exception, but it's magazines are specific to the size of the gun.
My general rule is any .45 pistol a barrel length under 4" should be using either a 185 or 200 grain projectile for expansion velocity while 4" and longer guns should use 200 to 230 grain bullets for their mass.
