The Century Arms AP5-P Navy is a Navy-pattern semi-automatic pistol chambered in 9mm Luger with a 5.8-inch cold hammer-forged barrel. It uses a stamped steel receiver finished in lacquer over manganese phosphate and follows K-pattern (MP5-style) proportions with a Navy-style ambidextrous grip. The barrel is threaded 1/2x28 with a 3-lug pattern for muzzle devices.

The AP5-P Navy draws attention for bringing MP5-style handling into a pistol format, and most owners come away impressed with how solid the action feels compared to a typical blowback 9mm pistol. Fit and finish on the stamped receiver gets mixed marks: some pistols run tight and clean out of the box, while others need a short break-in period before cycling settles down.

Ergonomics are a common talking point. The Navy-style grip and wide handguard make the pistol easy to control for its size, and the threaded barrel and Picatinny rail make it simple to add a light, optic, or brace. Owners who add a brace note that the pistol gets front-heavy once the extra hardware is attached.

Value is where the AP5-P Navy earns the most praise. Coming with spare magazines and a flash hider out of the box helps offset the cost, and K-pattern parts compatibility opens up a wide range of aftermarket accessories. The main complaint tends to be quality control variance between individual pistols rather than the design itself.
