We're the Remington XP's produced with a stainless steel action.

Looked at a XP-100 today in a local gun shop. The action looked to match what I thought was a heavy stainless steel barrel with a bead blasted finish. The action was greyish in color like the barrel and had also been bead blasted. The shop owner thought the action was a standard blued action that was stripped and bead blasted but I thought the action would have been shiny er in appearance.
I couldn't recall ever seeing a stainless XP for sale.
