If all I knew was that it was going to happen, and I had no way to avoid it, I would go with my SR9c and a couple of spare mags. The reason that I would chose this over an AR or a shotgun is that I figure that any sort of gun fight I may stumble into would be fairly close quarters where a long gun may prove to be more of a hindrance than an asset.
