My point is this: The .44 Magnum cartridge is essentially a long range cartridge. To get the maximun performance, the longer barrels are a must. Not only do they deliver maximum performance, but also extended sight radius. Whatever accuracy you derive from a 4" barrel, will be increased with a 6" or 7 1/2" barrel.
If it is desired to shoot .44 Special level ammunition, then a good .44 Special revolver is the better choice as to weight and convenience.
I have a 4" Model 29, and a 7 1/2" Ruger Blackhawk. The 4" gun has about 5,000 rounds fired through it. The Ruger over 17,000 rounds.
As to up-close power, a .45 Colt is a better choice, and if you are a glutton for punishment, it will serve equally well.
