I can't speak for others' polls but in this case, I put forth a list of what I currently have to work with for concealed carry. I may get more choices down the road but right now it is either a choice between these 4 or don't carry at all.
Can we assume that theses are guns you currently own? If so, you could easily trade any one of your guns for something better suited to carry. If that is not possible for whatever reason, I would carry the Sig. With the right belt and holster, and with the appropriate clothing you could probably make do with any of them. That would be a far better option than going unarmed in my opinion.
