Description

There aren't many firearms out there quite like the Stowaway. Dark Mountain Arms, the veteran-owned outfit started by the designer behind the Trailblazer Lifecard and the award-winning Pivot carbine, built this large-format bolt-action pistol around one simple idea: take up as little space as possible without cutting corners on quality. Pull the removable 5-inch barrel and the whole thing shrinks to 7.1 inches, small enough to tuck into a daypack, tackle box, or truck console organizer. Reassembly takes seconds, and at right around 2 pounds you'll barely notice it's along for the ride.

What Sets the Stowaway 9mm Apart

The left-side bolt handle looks unusual at first, but it's a smart touch that lets right-handed users run the action without breaking their firing grip. The single-action striker uses a manual cocking knob with a half-cock position, so you cock it deliberately for each shot. Up top, a Picatinny rail is ready for a red dot or pistol scope, and the muzzle wears 1/2×28 threads so a suppressor spins right on. Paired with subsonic 9mm, this little bolt gun gets impressively quiet. This SKU also ships with the 1913-style adapter rail already mounted on the receiver, a two-slot interface sized for folding stabilizing braces like the SB Tactical FS1913.

A Modular Platform, Not Just a Pistol

Because the Stowaway swaps calibers with just a barrel and bolt face change, this isn't a one-trick purchase. Dark Mountain Arms offers conversion parts in 5.7x28mm, so one receiver can pull double duty depending on what you're feeding it. Construction is a practical mix of aluminum, steel, and glass-filled nylon with a corrosion-resistant black finish that shrugs off weather on the trail.

Why the Stowaway Earns a Spot in Your Kit

For backpackers, campers, and anyone building out a compact kit, the Stowaway makes a strong case for itself. It's simple, tough, American-made, and does the packable survival gun job better than just about anything else in its weight class. Feed it your favorite 9mm and enjoy how easy this thing is to live with.

Frequently Asked Questions

Does the Stowaway 9mm come with a brace?

No, this model includes the factory-installed 1913-style adapter rail on the receiver, but the folding brace itself is sold separately. The two-slot rail was designed around braces like the SB Tactical FS1913, so adding one is a quick bolt-on job.

Can I suppress the Dark Mountain Arms Stowaway?

Yes, the 5-inch barrel comes threaded 1/2×28, which is the standard pitch for most 9mm suppressors. Since it's a bolt action with no reciprocating slide, it runs quieter than a suppressed semi-auto, and pairing it with subsonic 9mm makes it one of the quietest setups you can put together.

Can the Stowaway be converted to other calibers?

It can. The platform is caliber-convertible with just a barrel and bolt face swap, and Dark Mountain Arms currently offers the system in both 9mm and 5.7x28mm. That means one receiver can cover two very different roles depending on the barrel you screw on.

How small does the Stowaway pistol pack down?

With the barrel removed, the whole pistol measures just 7.1 inches long and weighs about 2 pounds. That's small enough for a daypack, glove box, or emergency kit, and it reassembles in seconds when you need it.
