 the Torus Tracker 692 multi-caliber. Comes with two cylinders. This one shoots 38 special and 357 magnum. The other one shoots 9 millimeter. Three inch barrel. Four ports on each side. Adjustable rear sights. There we go. Nice. I love it. I'm gonna push this button and pull forward and off comes the cylinder. This arm right here, end of the slot, push this button, drop it and now it is all set to shoot 9 millimeter.
