If I recall your other posts correctly, you're looking for a home defense gun, not a carry weapon. For home defense, I'd stick to the 4" to 6" range.
A 6" barrel will probably increase bullet velocity a bit, will be a little quieter (magnum ammo can be VERY loud), has a longer sight radius for more precise aiming, and may have less muzzle jump. However, a 4" revolver feels better balanced to me, and that's the length I prefer for general purpose.
