Florida-based Diamondback Firearms came to SHOT Show recently with a bevy of new guns for 2025. 

Building its revolver line, the company introduced both a 3-inch .357 and a 2-inch 9mm snub nose as well as DB15 rifles with 18-inch carbon fiber barrels and a collab with Knight’s Armament to add KAC’s cold hammer-forged barrels to their rifles.

The new Diamondback Self Defense Revolver, or SDR, line, was introduced last year just in .357/.38 caliber and only in 2-inch formats. The company has grown that to include 9mm guns that accept full-moon clips for loading/reloading and grow the barrel length to 3 inches. All SDRs run six-round cylinders and use a Kimber K6s-style push-button release.

Built for the personal defense market, the SDR line also boasts high-visibility fiber-optic sights.

As 9mm is a rimless cartridge, the new 9mm SDR ships with three TK Custom moon clips.

The company also had an exquisitely engraved model at the show that we got to lay hands on. Will it become an option? Anything is possible. 

 

MSRP for the new guns comes in at $821 for the new 9mm SDR and $837 for the 3-inch .357 Magnum.

 

New Rifles
 

 

The company introduced its DB15 series in 2012, and since then it has found success with the platform. New for 2025 is a collaboration between Diamondback and Knight’s Armament, with the latter providing its proprietary chambered, rifled, and chrome-lined cold hammer-forged barrel blank to Diamondback, which then completes the profiling process and assembles the rifle.

Standard features include a pinned gas block in a mid-length system, an anti-rotation S-rail with M-LOK slots, chrome-lined M16 BCG, and Magpul furniture (MOE K2 grip, CTR stock, and PMAG). 

 

Note the Magpul furniture. Barrel by KAC.
The barrel on the DB-15 KAC collab is a 16-inch 1:7 twist chrome-lined affair with a phosphate finish. Overall length is 32-35.5 inches, while weight is 6.53 pounds. 

 

MSRP on the Diamondback/KAC DB-15 is $1,547.

Also new is a DB-15 with an 18-inch 1:7 twist 416R stainless steel carbon fiber wrapped barrel. Running a .223 Wylde chamber and a soft-shooting rifle-length gas system, it wears Magpul furniture including a PRS-Lite stock. It also sports a 2.5-pound CMC single-stage drop-in trigger and a 15-inch S-rail handguard with M-LOK slots. 

 

It runs a PRS-Lite stock and a rifle-length gas system on a 18-inch barrel. 
The barrel production process starts with profiling a 416R stainless-steel barrel blank and wrapping it with carbon fiber strands infused with epoxy resin, which yields a lightweight barrel with superior strength and improved heat dissipation. 

 

MSRP on the Diamondback 18-inch carbon fiber DB-15 in .223 Wylde is $1,635.
