Most of the big calibers, in DA guns are absurdly heavy or large.
SA guns can be made into much more concealable packages, with more power for weight.
I like the idea of a bullet that's already .475-.510" in diameter, and, then may expand to the size of a two bore rifle bullet.
This is an exit hole from a .500", LFN bullet, 440 grains at 950 FPS thats a 300 win mag cartridge for size comparision:
.
And this perfectly illustrates just why you never wanna carry solid bullet loads for self-defense (against humans)! You do not want an exit wound from you SD round! You want that bullet to stay in the bad guy not sail down the street or into the next room and hit some little kid or something.
