I went looking at some reloading info, The 45ACP can be run up quite a bit more than I thought. I have always loaded either bullseye loads or standard mil-spec at 700-900fps. A 357 "seems" to have quite a bit more velocity. A full house 357 does indeed have some flash and noise especially in a short barreled pistol. I would guess a 45ACP +P etc would be rather snappy as well. Perhaps not the flash but recoil. I have settled on the 41 mag for hunting/backup, and the 38/357 with mostly 38's for range fun days
