Gonna have to agree with Lone Star...with a 10" barrel, the .357 Max. has my vote. With a 14" barrel, the 35 Rem. has my vote. I know that it's off topic, but I still prefer the .375 Win. over both (mine is a 14").
If you're worried about Regs. involving the use of handguns and their appropriate calibers, move here to PA...we don't have any of those silly rules regarding handguns and cartridge length, caliber, etc.(with the exception of semi's) .....yet.
