First Look: Diamondback Firearms DB FS Nine

Diamondback Firearms is introducing their newest firearm, the DB FS Nine. This full-size, 9x19mm striker-fired pistol features a polymer frame with integrated MIL-STD1913 Picatinny rail system and a flared magazine well.

The DB FS Nine's 4.75-inch barrel and 6.25-inch sight radius make it a versatile choice for competition, target shooting and self-defense purposes. Front and rear cocking serrations milled into its Melonited stainless steel slide enhance grip during manipulation.


Safety features of this double-action pistol include a firing pin block and trigger safety, while a cocking indicator located on the rear of the slide provides visual and tangible recognition of the firearm's condition. A small peep hole in the top of the slide also enables visual inspection of a cartridge in the chamber.



The Diamondback DB FS Nine won't break the bank with its competitive pricing of $483.34.
