Parkerized, not stainless. This is NOT one of the current guns with a plastic case, plastic holster, plastic mag holder, and 2 sets of grips; this comes with the original cardboard case, instruction manual, and 2 (blued) magazines. I've put no more than a few hundred rounds through it, mostly shooting cowboy matches (Wild Bunch). It has always been 100% reliable, with either factory ammo or my reloads (LRN bullets). The only modification I've had done was to install better sights (still legal for Wild Bunch traditional shooting, but much easier to see). MUST ship to an FFL dealer. PRICED REDUCED FROM $600.
