As usual, it’s pretty hard to disagree with Colion Noir. Unless you’re a Five-seveN fan, then, yeah. You’re boned.
I have a really soft-shooting centerfire gun that uses an interesting cartridge. It’s my .38 Special revolver. Generating about 200, 230 ft-lbs of force with common loads, it’s on par with the 5.7x28mm cartridge in terms of energy when fired from a pistol and, get this, you can even use black powder to load ammo. How’s that for exotic?
Plus it’s crazy-retro.
