I too looked at these guns, look like nice little pistols. I opted for a Ruger MKII 678 slab side target/gov model. The only sig I have is a Model p220 45acp. Sig makes a great weapon, I just liked the Ruger 22 better. Sorry I dont have first hand experiance with the little sig. I do know sig makes a great product, if the 22 is anything like the 45 it will be a great gun. The Ruger has a large aftermarket following, great upgrade options. Not so much with the sig. HTH.
