That guy is a hell of a shot. The gun is nice, but I'm more of a rifle person.
SIG556
This is what I carry around with me. Small enough to carry, with enough punch to make someone limp.
SIG P232 Stainless with SigLites
This is one of the best pistols I've shot.
SIG P226
Such an easy to shoot gun with great accuracy. Just a little too big to haul around with me.
