Diamondback DB0200P021 G4 DB9 9mm Sub-Compact Pistol with Nickel Boron Slide

Diamondback Firearms is proud to present the DB9 G4, a micro-compact 9mm pistol made entirely in the USA. Designed with safety in mind, the DB9 features a "ZERO-Energy" striker firing system with a mechanical firing pin block, a steel magazine catch to secure a sheet metal magazine and real windage-adjustable sights, all in a lightweight pistol. A steel trigger with dual connecting bars allows for a crisp, smooth, trigger pull. The DB9 features a FEA (Finite Element Analysis) designed slide and barrel that is stronger than any comparable firearm, resulting in durability with less felt recoil, and the absence of removable pins or tools makes field stripping easier than ever. The slide, barrel, and internal parts are coated to resist corrosion, making this pistol a lifetime investment.

The Diamondback DB0200P021 G4 DB9 is a compact 9mm pistol designed for discreet carry and dependable everyday performance. Its sub-compact profile combines a black polymer frame with a lightweight construction, making it practical for users who prioritize portability without giving up familiar pistol handling. The right-hand configuration and black polymer grips provide a secure, comfortable interface.

This Diamondback G4 pistol features a 3.10-inch stainless steel barrel and a serrated stainless steel slide finished in durable Nickel Boron. The slide’s serrations support positive manipulation, while the matte black frame and contrasting metallic slide create a clean, functional appearance. A 3-dot contrast sight configuration helps provide a straightforward sight picture for defensive and range applications.

The DB0200P021 uses a striker-fired system with double-action operation and a firing-pin safety. Its 6-round capacity supports the pistol’s slim, compact format, while the short overall profile is suited to concealed-carry-oriented use where applicable and in accordance with all local laws. The combination of a polymer frame, stainless components, and compact dimensions makes the G4 DB9 easy to transport and handle.

For owners seeking a small, feature-focused 9mm pistol, the Diamondback DB0200P021 offers a balanced combination of compact size, practical controls, corrosion-resistant slide treatment, and accessible sighting. Review all applicable federal, state, and local laws before purchase or transfer, and ensure the firearm is handled, stored, and used only by qualified individuals.
