The Pietta King Trio (brand part no. PSA5441) is a single-action revolver built around a convertible cylinder system, letting shooters fire .38 Super, 9mm Luger, or .357 Magnum/.38 Special from the same 5.5-inch barrel. Pietta ships the King Trio with three interchangeable six-shot cylinders, so switching calibers takes only a cylinder swap rather than a different gun. A case-hardened frame pairs with a brass backstrap and trigger guard, and a rich walnut grip rounds out the classic single-action styling. Among revolvers, the King Trio favors shooters who want caliber flexibility in one Old West-style sidearm.
