These Sig pistols are extremely good pistol for conceal carry! Did yours come in that case? I would also recommend you getting a upgraded holster if you plan on carrying. Crossbread holsters would be a good place to start http://crossbreedholsters.com/
Looks good. I like the external hammer. Means you can keep it in condition #2, and then when you draw it just pull the hammer back, and then fire. I see that its a single action. I generally prefer double actions for all my handguns (pistols and revolvers).
