I should add that since i wrote that original review of the .357 big boy a year ago, i have picked up the .44 mag version.
Same great experience with a bit louder noise. A bit more recoil but still a non-issue even for the most timid shooter. Love it, too.
I tend to shoot the .357 more due to cheaper ammo.
I would like to find the .45 colt version since i reload that caliber and it would complete the big boy hat trick LOL
