I think what has been unstated in this thread so far, is that (to my understanding) the .45GAP round is a 200 grain loaded to +p specs, to "duplicate" the 230 gr .45 acp round.
My chrono averages for 5 shots:
Glock 38:
Winchester 230 Ranger T @ 837 fps/ 358# KE
Speer Gold Dot 200 @ 949 fps / 400# KE
Speer Gold Dot 185 @ 1,062 fps / 463# KE
Glock 30SF
Federal Hydra-Shok 230 gr. @ 811 fps / 336# KE
Federal Hydra-Shok 185 +P @ 1,005 fps / 415# KE
Remington Golden Saber 185 +P @ 1,008 fps / 418# KE
