Dark Mountain Arms Stowaway | 9mm Single-Shot | 5 in Threaded

The Dark Mountain Arms Stowaway is a bolt-action, single-shot handgun chambered in 9 x 19mm designed for compact transport and straightforward caliber conversion. It uses a removable, threaded 5-inch barrel and a 1913 brace adapter to allow fitting of a foldable brace where legal. The platform includes an optics-ready Picatinny rail and is built from aluminum, steel, and GF nylon with a corrosion-resistant finish. For an optic that pairs well with this pistol, consider a durable red-dot such as the Vortex Venom 3 MOA for fast target acquisition under $1,000.
