Derya Arms, the Turkish firearms manufacturer known for its modern MK-12 and Lion semi-automatic shotgun series shotguns, introduced its first striker-fired pistol, the DY9 in 9mm Luger. With the DY9 model series, Derya enters the highly competitive market of service pistols with polymer frame. The pistol comes as a full-size model with interchangeable backstraps. Slide and barrel are black-nitrated. The buyer can choose between various grip frame variations in different colors (FDE, olive, black, gray). The frames all have an accessory rail in Picatinny format on the dust cover, but differ in the texture of the side surfaces and the front strap, as well as the checkering of the interchangeable backstraps. The slide also feature a variety of options in terms of sights and serrations, with the front serrations giving way to skeletonization for the more sporting-oriented user. In each case, the interchangeable front sight is fixed and the rear sight sits in a dovetail. The striker-fired pistol also features a safety integrated in the trigger.
