What makes the 15-2 distinctive Unlike a conventional revolver with a permanently fixed barrel, the 15-2 uses a tensioned barrel system. The barrel and shroud are separate components, and the barrel is secured to the frame while the shroud surrounds it. This design was intended to provide consistent barrel alignment and allowed different barrel/shroud assemblies to be used with the same revolver. The 15-2 was offered in numerous configurations, so barrel length, shroud style, sights, grip, finish, and markings can vary considerably between individual examples.
