First of all, check your State regs. In Ohio, one is not allowed to carry a handgun for "backup" whilst deer hunting the exception being CC license holders who are carrying concealed for self defense. Also, for deer hunting in Ohio, the barrel has to be a minimum of 5 inches long.
I like crossdraw or strong side belt or paddle holsters in general. One of my favorite carry guns is a S&W 357 Mag. with a 2 inch barrel that I carry in a paddle holster that works for strong side or crossdraw. On the other hand, a Ruger Redhawk with a 5.5 inch barrel isn't too long to be handy in my opinion.
Theoretically, a short barreled handgun is just as accurate as one with a longer barrel. Practically speaking, many have more difficulty getting a good sight picture with the shorter barrel and, the velocity being a bit less, the range for accurate shooting will probably be a bit less as well. For distances of 25 yards or less, velocity with a 2.5 inch barrel should be sufficient for accurate shooting though.
