This is a Caspian Damascus slide on a Caspian titanium frame, Kart barrel with an EGW bushing, The hammer and sear are Berryhill. The GS is an EB. The grips are maple by Tony Cap in Ohio. All the carbon pieces are high polished blued. The frame and slide are untreated. The gun shoots awesome with Stan Chen's ASYM ammo at fifty yards. Enjoy.
