Didn't read that enough. Per Ruger's site: Sold in a two-gun set with consecutive serial numbers with "SASS" prefix, shipped together in a commemorative, red two-gun case.
It has "a high-gloss, stainless steel finish VaqueroŽ with lower and wider Montado-style hammer, 4.62" barrels, and wider (.14") rear notch sights." I also believe the grip frame is the stand one and not the grooved one on the Montado. Not that it's a big deal but the grip medallions are unique to this model too.
