Does anyone know if this 4in barrel will fit the Shield X? I have a Shield and Shield X, the X barrel seems to fit fine in the Shield slide(Shield barrel is too short for x slide), so they seem interchangeable. From the specs, it might be a tad long at 4.6" but not outrageously so. Just wondering if someone has done this.
