I simply can't imagine shooting a a snubnose big magnum.
My Redhawk .44 IS 7 1/2. My Super Redhawk .454 is 10 inches.
I like for my gunpowder's energy to push the bullet, not to make a lot of wasted flash and bang.
And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
