Nighthawk Custom now sells the Korth Mongoose revolver in .44 Magnum through a partnership that pairs German manufacturing with American finishing and distribution. Locksmith Willi Korth started the firm in postwar Ratzeburg and produced revolvers by hand from solid steel billets, with each gun taking months to finish.

The Mongoose has a hammer-forged barrel, a six-round cylinder, an adjustable rear sight, and a DLC surface treatment. Turkish walnut stocks and a polished trigger complete the design. It comes in 3-inch, 4-inch, and 6-inch barrel options and lists for about 4724 dollars, with specifications posted on the Nighthawk Custom site.
