There's a real difference between a pistol that's technically concealable and one that actually disappears into your carry rotation. The Diamondback DB9 Gen IV leans hard into the latter. At 5.73 inches long, 4 inches tall with the flush-fit mag, and less than 0.9 inches wide, it sits comfortably in the same size territory as .380 pocket guns while actually running 9mm. The unloaded weight of 13.4 ounces means most people won't notice it through a full day of carry, whether that's in a pocket holster, IWB, or as a backup gun.
Diamondback put real thought into the Gen IV update. The slide lock lever, which was absent on earlier generations, is now there. The grip texture was redesigned for a better hold, and the front and rear slide serrations give you positive purchase even if your hands are wet or sweaty. The sights are a genuine 3-dot setup with a wide U-notch rear that's Glock 42/43 compatible, so if you want to swap in night sights or fiber optics down the road, you have plenty of options without custom machining. The steel trigger runs on dual connecting bars for a consistent pull, and the short reset makes follow-up shots manageable for a gun this size.
The Nickel Boron finish on this particular model does more than just look sharp against the black polymer frame. NiB coatings are well regarded for their hardness and slickness, which helps with both corrosion resistance and cycling. The slide, barrel, and internal parts all benefit from corrosion-resistant coatings, which matters when this thing is riding against your body all day. The barrel itself is stainless steel with a 1:10 right-hand twist, and the FEA-designed slide and barrel are engineered to be stronger than traditional designs while also helping reduce felt recoil for a pistol this light.
Diamondback built this pistol around their ZERO-Energy striker system, which keeps the striker at rest until the trigger is deliberately pulled, paired with a mechanical firing pin block for a second layer of protection. The slide release and magazine release are intentionally recessed to prevent accidental activation during carry, which is the right call on a deep concealment gun. Field stripping requires no tools and no removable pins, which keeps maintenance simple and accessible for any skill level. The DB9 Gen IV is made in the USA and ships with a 6-round single-stack magazine.
Yes, the DB9 Gen IV is rated for +P 9mm ammunition. That said, like any lightweight micro-compact, running a steady diet of +P will add wear over time. Most owners use standard pressure loads for practice and reserve +P hollow points for carry duty, which is a sensible approach with a pistol this size.
Several well-known holster makers produce options for the DB9 Gen IV, including DeSantis, Blackhawk, and a handful of dedicated kydex makers. The DeSantis Nemesis pocket holster is a popular choice given how well the DB9's slim profile lends itself to front-pocket carry. IWB and appendix carry holsters are also widely available for belt carry.
Yes, and it's one of the nicer features of the Gen IV update. The sights are compatible with Glock 42/43 aftermarket replacements, which opens up a wide selection of tritium night sights, fiber optic options, and blacked-out carry sights without needing any custom machining. The factory 3-dot sights are actually quite usable for a gun this size, so it's an upgrade when you're ready rather than a necessity out of the box.
Nickel Boron is a hard, slick coating that handles corrosion and wear well, making it a solid choice for a carry pistol that sees daily skin contact and humidity. It also has a naturally lower friction surface compared to bare steel, which can contribute to smoother cycling. The two-tone look with the black polymer frame is a nice bonus if you prefer something with a bit more visual contrast.
Yes, the Gen IV added a slide lock lever that earlier generations of the DB9 lacked. This was one of the more requested improvements, and it makes it easier to verify the chamber is clear and speeds up reloads. The controls are intentionally recessed to prevent accidental activation during carry, so they are a bit stiff by design.
The DB9 Gen IV is legitimately one of the smallest 9mm pistols available, measuring just 5.73 inches long, 4 inches tall with a flush magazine, and 0.9 inches wide. That puts it in the same dimensional range as several .380 pocket guns while chambering the more capable 9mm cartridge. It is notably smaller and lighter than the Ruger EC9s and Glock 43, and thinner than most of its direct competitors.
