RH thumb release cylinder, RH tilt muzzle up, while LH grabs loaded moon clip from same location as mags are kept, RH tilts muzzle straight down, LH throws loaded moon clip in, (shake only if required) LH closes cylinder reacquires grip then bang. Mostly same hands doing same as semi-auto reload. If empties don’t fall (rare on 45ACP moon clip) then bump ejector with LH before throwing in reload.
