Diamondback DB9 Features

The Diamondback Firearms DB9 is a subcompact, polymer-framed, double-action pistol that operates on a short-recoil action with a tilting 3 inch barrel.  Designed for concealed carry, this gun either has low-profile components or rounded edges to make sure it can easily be retrieved from a holster without snagging on clothing or other obstacles.

Diamondback DB9 Capacity

The Diamondback DB9 is chambered in 9x19mm Parabellum (9mm Luger, 9x19mm NATO) and feeds from a single-stack magazine that holds 6 rounds.  This tiny little pistol has no issue feeding ball ammo, hollow points and other bullet types, however its small barrel and light slide make firing +P ammo quite a dice roll. 

Diamondback DB9 Ergonomics

The grip of the DB9 is so small that an hour at the range may cause your hand to cramp up, but this gun was designed for concealment above all else, so comfort wasn’t the focus for this gun.  The controls are all very small so they won’t get in the way on the draw, though they’re on the edge of being too small.  Keep in mind that this is a backup gun and not a competition pistol.

Diamondback DB9 Fit & Finish

Between one portion of the market preferring small guns and that portion having an affection to bright colors, Diamondback Firearms decided to produce this pocket pistol in something other than black-on-black.  The slides and barrels are available blued or in stainless steel and the frames can be found in any of the different colors that are typically found on guns.
Fit and Finish

Diamondback DB9 Concealability

The DB9 measures less than 1 inch wide. 4 inches tall and 5.6 inches long making it extremely easy to tuck away where nobody will see it.  Whether it’s inside your belt, in your pocket, on your ankle, in your purse or in a fanny pack, as long as your attire isn’t skin-tight, nobody will ever know you got that gat on ya without a metal detector.
