Dark Mountain Arms Stow Away 9Mm 5 Tb Brace

The Dark Mountain Arms Stow Away 9mm pistol with brace adapter is a modular, bolt-action single-shot platform built for shooters who value packability and versatility. Unlike conventional fixed designs, this compact pistol breaks down—the barrel detaches to reduce overall length for transport, storage, or caliber conversion, making it a genuinely adaptable tool for the range, backcountry, or truck. The 1913 Brace Adapter allows you to add a foldable brace, helping manage recoil and improving controllability (note: all NFA regulations apply). Whether you're working with limited space, planning an overlanding trip, or want a modular platform you can reconfigure, the Stow Away delivers thoughtful engineering without compromise.

Built from aluminum, steel, and glass-filled nylon with a corrosion-resistant finish, this pistol is designed to be durable and lightweight—just 2 pounds. The bolt-action with half-cock safety is straightforward and reliable. A 1/2×28 threaded muzzle accepts suppressors, and the integrated Picatinny rail lets you mount optics or other accessories. Caliber swaps are straightforward: change the bolt face and barrel, and you've got a new platform without buying a whole new gun.

Dark Mountain Arms manufactures this pistol in the USA, and their veteran-owned operation shows attention to detail. If you're after a no-nonsense, space-efficient single-shot with real modularity, the Stow Away 9mm steps up to the challenge.
