About
What it is, and why it matters
The Korth Mongoose is a German-made double-action/single-action revolver chambered in .357 Magnum and .38 Special. Positioned as the most accessible model in Korth's premium lineup, every component is fully machined from billet steel, and an interchangeable cylinder system lets the shooter swap the .357/.38 cylinder for a 9mm Parabellum cylinder. Imported into the United States by Nighthawk Custom, it is offered in barrel lengths from 2.75 to 6 inches with a ventilated rib, DLC finish, and a precision-tuned trigger.
Korth revolvers are renowned among collectors as some of the most expensive and finely fitted handguns in the world. The Mongoose was introduced as the brand's entry point, bringing the marque's billet-steel construction and interchangeable-cylinder design to a slightly broader market through the Nighthawk Custom partnership.
Imported and marketed in North America by Nighthawk Custom. Optional 9mm cylinder ships standard with many configurations.
