My brother purchased one earlier this year to replace his P220ST as his duty gun. This would be his 5th P220 variant. He seemed very excited when it arrived. The OD frame is actually very nice. I was impressed with how the color came out! The internals are either Phosphated or Nickel'd for corrosion resistance. The trigger pull felt as good as any other SIG that I'd felt. I don't recall if the trigger was flat or serrated. The front strap has vertical
checkering (for lack of a better word, it's not really checkered). I really liked that the un-checkered vertical checkering
; it really felt good in my hands.
The thing that I didn't really care for is that the rail is a true M1913 rail. All other SIG rails are not quite standard M1913 rails. My brother had a difficult time fitting his rail-mounted light on it. In the end, the metal light brackets may have scratched the finish on the dustcover. I don't know how the M1913 rails would fit in a standard holster. His duty holster holds the pistol with light attached to it. I don't know if a standard M1913 rail will provide any benefits over the current SIG rail.
While I haven't gotten a chance to put some rounds through it, he has given me a range report. In the 300 rounds that he put through it, he didn't have any failures. The pistol shot dead-on. It showed as much quality as any of the other SIGs that he owns.
Is it worth it? It really depends. I don't think that I would have spent the extra money on it. I just don't view the
upgrades as value-added. They're nice. They
may (or may not) have some performance enchancing properties. I just feel that it is a marketing ploy by Sigarms. Any enhancements were aesthetic or feel-good. The P220Combat is definately a cool pistol, I just don't think it is a step-up from the standard P220. Don't get me wrong, I'd love to own one. I just don't feel it is worth the additional money.
Good luck with your search!
