I have the P220 Combat and love it. One reason I wanted that model rather than the standard P220 is that it has a mil-spec M1913 Picatinny rail so it will fit a wide variety of attachments; most SIG pistols have a proprietary rail that that doesn't fit perfectly with third-party attachments. The color scheme also looks great. All the components are coated for corrosion resistance. Of course, it has the great accuracy, reliability, and ergonomics you'd expect from any P220 model (and SIG in general). I felt I got my money's worth despite the hefty price tag.
