Maybe it's the 1911 guy in me, but I've always considered the Sig full sized guns near "commander" length guns anyway. So, why not have SAS models with 4.4 inch barrels? I love the look and the sight radius that the extra half inch gives and IMO that much barrel length doesn't matter as much as grip and width when concealing.
So who's with me? You wanna sexy SAS full sized p220 or p227 like I do?
I figure it should be a no brainer considering how the W. German Sigs are seen as great looking.....add the anti-snag treatment and it would fly off the shelves IMO.
