My Marlin 94 has never had any problem with either .357 or .38 loads. I have not tried to shoot full wadcutters, but the other bullet profiles work just fine. I put a peep sight on mine, since a scope is not needed for the range of the cartridge. I think a scope would unbalance the gun and negate the easy carrying. A 158 grain bullet in the .357 comes very close to the origiinal .30-30 balistics. With a pistol cartidge, barrel length will probably have less influence on velocity than individual variation between guns. You could probably find a tightly made 61 inch barrel that shot faster than a sloppy 24 inch barrel. If in doubt, get ten yards closer and any velocity difference will be negated. If I were to get a stainless rifle, I would have it black chromed, so it would look right.There are a number of coatings on the market that will protect a blued steel gun about as well as stainless, and cost a whole lot less.
