Local gunshop has a Sig 220. It's used but excellent to new condition. It is however 9MM. I'd only seen 220's as 45's and in fact have one. I also have the 226 in 9MM. I'd never trad a double column for a single but either 220 just fit my hand better than the 226. Has anyone seen a 220 chambered for 9MM. He only has one magazine for it and was unable to find any in catalogs he was using. I'm guessing this is a pistol that's several years old and mags won't be currently listed. I'm wonderig how hard they will be to come by. They basically look like 45 Sig 220 mags with a grove down each side to let 9MM's in but keep 45's out. It's got the older black checkered plastic grips but aftermarket will fit it. Sights are conventional with rear bar and front dot. Very smooth action, I'd just never seen 220's in anything but 45 ACP. Any info welcomed. Thanks
