Diamondback Firearms DB9 G4 9mm Luger Pistol, 3″ Barrel, 6+1-Round, DB0200P251

Product Description

The Diamondback Firearms DB9 G4 is a compact 9mm Luger pistol with a 3″ barrel and a 6+1-round capacity. It is striker fired, weighs 11 oz and measures 5.6″ overall. The frame is polymer, so the pistol stays small and light in the hand and on the belt.

What sets the G4 apart

The barrel is 410 stainless steel, and the slide wears a blue Cerakote finish. The grip has an updated texture for a firmer hold. The magazine catch is steel, and the magazine follower is orange, so you can see at a glance where the spring sits. The trigger has a short reset, and a manual safety is fitted. Sights are fixed, with a dot sight and a fixed 2-dot setup. One single stack magazine is included.

This pistol suits shooters who want a slim 9mm for concealed carry, a backup gun, or a lightweight pistol to keep close at home. The short 3″ barrel and 5.6″ length keep it easy to manage, while 9mm Luger gives you a wide choice of ammunition.

Good gear to pair with it includes a holster molded for the DB9 G4, spare single stack magazines, a belt that can carry a pistol, and a basic cleaning kit. A lockable case or small safe is a sensible addition for storage at home.
