Revolver barrel twists

[TexasPatriot.308]

I hunt with Ruger Blackhawks in .357 mag (convertible to 9mm), a .44 mag and a .45 colt. I am leaning towards a small revolver for carry, looking at 9mm, .357 mag and .45 acp. Maybe a dumb question, but are the twists different on revolvers versus semi autos?

My hunting revolvers are 5.5 to 7.5" long barrels. I realize there cant be much twist in a 2 inch barrel.
