To keep it on topic, 22 mag out of a pistol is brutally loud. My dad has a single six convertible and after shooting a possum without ears in with 22 mag I switched to 22 shorts.
I have a 357 4" sp101 ruger that's not a bad woods gun but a little heavy. You might want to look into a 32, I'm starting to. Not as much blast on the ears but good power for rabbits.
Single six in 327 mag looks interesting however if it came with a shortish barrel and birdshead grip.
