I've seen both the Armory Coat and Stainless TRPs. The photos give the impression that they are of the Armory Coat version, but the guns I saw were MUCH darker. The Stainless TRP has a nice matte finish that looks very similar to the photo gun.
Both are very nice, but the Stainless version was about $150 less. Still about $1250 here at my local shop in the PRK
