I have not been keeping up with current ammo.
What is the recommended round for the .45 out of a sig P-220 these days?"Out of every hundred men, ten shouldn't even be there, eighty are just targets, nine are the real fighters, and we are lucky to have them, for they make the battle. Ah, but the one, one is a warrior, and he will bring the others back." -- Hericletus, circa 500 BC

Cor-Bon's DPX line gets very high marks for barrier penetration, penetration in soft tissue, expansion, and weight retention—with an added bonus that the bullet's relatively low weight (thanks to it being homogeneous copper) means that you get decent velocity from short-for-caliber barrels (relative to a standard 1911's 5" barrel). The downside to the DPX line, especially the "Thunder Ranch" 185gr. .45ACP load, is that it's more expensive than other modern hollow points.
A cheap way to get DPX's, though not loaded quite as hot as the one's from Cor-Bon, would be to get a box (or more) of Magtech First Defense.
I haven't heard anything about Hornady's new "Critical Defense" line, other than advice from the factory that it shouldn't be used in 1911's which don't have ramped barrels.
Other than that, most modern hollow points (e.g. Remington Golden Saber, Speer Gold Dot, Winchester Ranger, Winchester PDX1, Federal Hydrashok, and Federal HST) are available in weights from 185-230 grains. All will do very well when used against an attacker; you just need to determine whether you favor velocity over mass. It is said that Remington's 230gr. Golden Saber load has terrible muzzle flash, but I can't comment on this claim.
One last note: this post links to Cabelas because I remembered seeing the linked ammunition on their site recently.
EDIT: You might want to post that question in the Armory.
