The DIAMONDBACK DB9G4 is an extended replacement magazine specifically designed for the Diamondback DB9 Gen 4. That specific fitment reduces wobble and misfeeds that can accompany generic aftermarket mags. At a price of $18.89, it’s an affordable, mission-focused upgrade for carry or range use.

Fit, function, and field reliability

Because this magazine is marketed as an extended replacement for the DB9 Gen 4, it’s built to interface with the pistol’s feed lips and magazine catch geometry. That reduces the need for spring tuning or feed lip reshaping. In practical terms, an extended magazine can improve reload ergonomics and provide a slightly longer purchase surface for more positive control during high-stress manipulation.

Material and maintenance considerations

While manufacturer specifics are limited, replacement magazines intended for defensive pistols are typically made from durable steel or high-strength polymer with a robust spring and follower. Regular maintenance—wipe down, light lubrication on the spring, and inspection of the follower—keeps the mag feeding reliably through many cycles.
