Here's what Sig is doing on the 320... 15 rounds (cool). OAL 8.5 inches (WTF).
Granted I think I've read 10mm likes more barrel to reach its potential, Sig seems to feel this market is limited to hunters and serious "long range" target shooters only, who split hairs over that.
Yeah I get it, but I'd probably own a DA/SA Sig in 10mm and not a Glock 20, or maybe even a 320 in 10mm some day, if they just provided 10+ rounds in a normal sized pistol. They aren't gonna compete in any other market by only offering them in "full size plus".
For shooters and hunters looking for performance to the power of 10.
