Saw this one recently:
The Best Handgun Caliber - A Real World Study ()
Not because I have any chance of owning one (don't even know if I would if I could), but because it is one of my interests.
So anybody here who owns a .454 Casull?
LOL! I wouldn't put too much credence in that video. The best self defense handgun is the one that fits your hand, you are familiar with, and practice regularly with, regardless of caliber.
.454 Casull? LMAO! Perhaps if you are hiking in Grizzly country.
