Note: This shell is not compatible with our ShapeShift series. It will only work with Cloak holster bases. Revolvers and semi-autos are now on separate interchangeable shell systems. As of Jan 1, 2015, revolver shells cannot be swapped for semi-auto shells and vice versa, as they require different holster bases.Already have a Cloak base and just want to be able to use that same base to carry a different firearm?
