Buffalo Bore has a variety of +p rounds, with this one having the highest energy:
.45 ACP +P Ammo - 185 gr. J.H.P. (1,150 fps/M.E. 543 ft. lbs.)
Seems like 230 gr loads are the most proven in .45 however, and it was never really meant to be very fast/high pressure.
The Holy Triumvirate for me remains these 230 gr + P loads:
Federal HST
Gold Dot (they also have a very nice 200 gr +P)
Win Ranger T
