Description

There's a short list of handguns that can genuinely claim to be true pocket 9mms, and the DB9 Gen 4 is near the top of it. At just 5.73 inches long, under 0.9 inches wide, and 13.4 ounces with an empty magazine, it goes places that even the Glock 43 can't quite reach. The single-stack design keeps the profile remarkably thin, and the Jesse James Civil Defense Blue Cerakote frame with a black nitride stainless steel slide gives it a two-tone look that's genuinely easy on the eyes.

Diamondback made meaningful upgrades when they landed on the Gen 4. The slide now features front and rear serrations for a solid purchase when racking, and the sights were completely rethought. Gone are the tiny vestigial sights of earlier generations. In their place are three-dot steel sights built on a Glock-compatible footprint, which means aftermarket night sights and other upgrades are readily available. The slide also locks back on the last round, a feature missing from earlier DB9s. The beavertail on the polymer frame helps prevent slide bite and improves the grip angle, and the front and rear stippling gives you something to hold onto.

The action is a Zero-Energy striker-fired system, double-action-only in feel, with a mechanical firing pin block as a passive safety. The trigger pull runs around 5.5 to 7.5 lbs depending on the source, with a shorter reset than older generations. The 3.1-inch stainless steel barrel has a polished feed ramp to help cycling, and the entire pistol is rated for 9mm +P loads. The recoil spring is a captive design, which makes field stripping noticeably easier than the original platform.

This is purpose-built for deep concealment. It works in a pocket holster, IWB, ankle carry, or purse carry. People running it for gym carry, hot weather carry, or as a backup to a larger gun consistently note that its light weight makes it easy to forget you're carrying at all. Every DB9 Gen 4 is made entirely in the USA at Diamondback's facility in Cocoa, Florida.

Frequently Asked Questions

Does the Diamondback DB9 Gen 4 fit in a standard pants pocket?

Yes, and that's really the whole point of this pistol. At 5.73 inches long, 4 inches tall with a flush magazine, and under 0.9 inches wide, it fits comfortably in a front jeans pocket with a pocket holster. It's been compared to the size of a large cell phone in your pocket. A dedicated pocket holster is still recommended to keep the gun oriented correctly and protect the trigger.

What sights come on the DB9 Gen 4 and can they be upgraded?

The Gen 4 ships with three-dot steel sights that are windage adjustable. More importantly, they're built on a Glock-compatible footprint, meaning a wide range of aftermarket sights including night sights will fit without any gunsmithing. This is a significant upgrade over earlier DB9 generations, which had very low-profile sights that were hard to use.

Is the DB9 Gen 4 rated for +P ammunition?

Yes, the DB9 Gen 4 is rated for 9mm +P ammunition, which is a meaningful improvement over earlier generations. That said, running +P in a 13-ounce pistol is going to feel snappy, so most people stick to standard pressure loads for range work and reserve the hotter stuff for carry ammo if they use it at all.

What is the Jesse James Civil Defense Blue finish on this DB9?

It's a Cerakote H-401 finish applied to the polymer frame, giving it a deep, rich blue color that Diamondback markets under the Jesse James Civil Defense Blue name. The slide is a contrasting black nitride stainless steel, creating a two-tone appearance. Cerakote is a durable ceramic-polymer coating known for corrosion and wear resistance.

How does the DB9 Gen 4 compare to earlier DB9 generations?

The Gen 4 brought several real improvements: upgraded Glock-compatible three-dot steel sights replaced the old hard-to-see sights, front and rear slide serrations were added, the recoil spring became a captive design for easier field stripping, and a slide stop lever was added so the slide locks back on the last round. The grip texture was also revised on the front and rear strap. Most people who have owned earlier DB9s consider the Gen 4 a substantial step forward.

What holsters work with the Diamondback DB9 Gen 4?

Because of its slim, flat profile, the DB9 Gen 4 works well in a variety of carry styles. Pocket holsters from companies like DeSantis and Blackhawk are commonly used, and IWB and ankle holsters are also viable options given the pistol's light weight. Diamondback works with several holster makers to ensure fitment, and the DB9's slim dimensions mean it disappears even in lighter clothing.
