Nighthawk Custom Korth Mongoose 4" Barrel 357 / 9mm Revolver 0155

Out of Stock


This is a new Korth Mongoose. The revolver is new and unfired. Double action/single action operation with light, ultra smooth double action pull. Ergonomic rubber Hogue grips. Windage adjustable rear sight. Beaded front sight. 4 inch barrel. Comes with a 9mm interchangeable cylinder.



The Korth Mongoose is a revolver offered in 3”, 4”, 5.25”, or 6” barrel configurations. Chambered in .357 Magnum/ .38 Special, the cylinder holds six rounds of ammunition. It is also available with a unique interchangeable cylinder system that allows for .357 Magnum/.38 Special and 9mm, to be interchanged in a flash. The Mongoose provides a level of versatility not seen in any other revolver on the market. This is a revolver that harkens back to the days when a revolver was a hand-built piece of functioning art. The frame and all parts are fully machined from the finest billet steel available. The trigger face is high polished and the smooth action is something that will make a lasting impression to even the most experienced competition revolver shooter. Standard with black DLC finish, the superior craftsmanship and material are clearly evident.

Great gun. Great buying experience from Gunprime.

I have owned and shot many different .357 mag. pistols in my life but I have never shot any that compare to the Korth "Mongoose". The trigger pull is the smoothest I have ever felt (that includes the Manurhin MR73). This revolver has to be the best built magnum in the world today. Expensive, but worth every dollar.
