I've also yet to try the 320, but really want to. It's just hard to spend more money foI9r a heavier, bigger gun with less capacity. Sub compact vs baby Glock, the Glock weighs less and has one or more rounds standard capacity than the Sig. And that continues head to head up the scale.
And a word on .357 Sig. With it's 40 S&W casing bottlenecked down to it's 9mm slug this sizzling cartridge feeds perfectly and flies faster than either of it's predecessors. Typical defense rounds have muzzle velocities of 1350 fps amd muzzle energies of over 500 ft-lbs. As compared to the 9mm at 1150 fp
