I think ole JD misspoke, happens to the best of us. The P220 is essentially the .45 P226. They are nearly identical except for the single stack magazine of P220 instead of the double-stack 9mm/.40/.357SIG of the P226.
Both are super weapons that have been battle tested with years of service in military & law enforcement. I carried the P220 and prefer the slimmer grip of the single-stack, but I think you will be well pleased if you decide to purchase a P226. My choice would probably be the 9mm because it is the original chambering for the gun, as well as cost and availability of ammunition.
I really like the two-tone because I think it looks sweet. The Oklahoma Highway Patrol used to issue the P220 in two-tone, but went with all black guns when they transitioned to P226 in .357SIG a couple years ago.
Here is a P228 like JD carried, with the two-tone finish (although my 220 and the OHP guns didn't have the sweet wood stocks).
