i can't think of any that isn't off the top of my head, although i'm sure there are some really hot +p loads out there, but they might cause some problems with some of the older 1911's.
Hirtenberger used to make some radical hot ammo. Their L7A1 9MM +P+ ammo was intense, probably the hottest ammo i've ever shot. Was supposed to be only used in open bolt 9mm SMG's but some guys tried to use it in normal 9mm pistols and it destroyed the gun.
