The Mk 22 Mod 0 “Hush Puppy” is a U.S. Navy suppressed pistol based on the Smith & Wesson Model 39 and chambered in 9×19mm Parabellum. It was built as a specialized stealth sidearm, combining a detachable suppressor with raised sights and a slide-lock feature to reduce the mechanical noise of cycling. The Mk 22 is best known for Vietnam-era Naval Special Warfare use as a quiet, close-range option for sentries and guard dogs.

HISTORY

The Mk 22 Mod 0 was developed in the 1960s as Naval Special Warfare looked for a suppressed handgun that was more capable than .22-caliber “silent” pistols but still compact enough for clandestine carry. Using the Smith & Wesson Model 39 as a base, the Navy created a modified package centered on a threaded barrel for the Mk 3 Mod 0 suppressor, plus taller sights so the suppressor would not block the sight picture. A defining feature of the system was a slide-lock device that could keep the slide from cycling, sacrificing rapid follow-up shots in exchange for reducing the clack of the action.

During the Vietnam War, the Mk 22 Mod 0 was issued in limited numbers for missions where noise discipline mattered, and it is most often associated with SEAL operations. It was paired with specialized subsonic ammunition (Mk 144 Mod 0) using a 158-grain green-tipped FMJ bullet, and the suppressor system used replaceable components that required periodic servicing to maintain effectiveness. While never a general-issue sidearm, the “Hush Puppy” became one of the best-known suppressed handgun systems of the era and influenced later thinking about purpose-built suppressed pistols.
