The Thunder Five is a five-shot revolver engineered to handle both .45 Colt cartridges and .410 shotshells. Its approximately 3.2 inch extra-long cylinder is purpose-built for .410 compatibility while maintaining DA/SA operation with an external hammer.
Construction is robust, using investment-cast steel for the frame and an integral investment-cast rifled barrel. The finish is a matte phosphate/parkerized two-tone treatment on the frame and other steel components, offering a uniform, utilitarian appearance.
Controls and safety features include a transfer bar and a frame-mounted manual hammer-block safety lever, an uncommon combination on revolvers. The top strap is ventilated/skeletonized and incorporates a trench sight channel for a low-profile sighting system.
Markings include "THUNDER FIVE" and "MILI PINEY FLATS, TN." Originating in the early 1990s in the United States, this model predates later .410/.45 revolvers and is often sought by enthusiasts for its distinctive configuration.
