Derya Firearms DY9.ISL.US DY9 Island Kit 9mm Luger 15+1 3.86″ Black Melonite Steel Barrel, Black Melonite Steel Optics Ready/Serrated Slide, Black Melonite Polymer Frame, RMR Footprint

Overview

The Derya DY9 Island Kit is a striker-fired semi-automatic handgun chambered in 9mm Luger, featuring a 3.86-inch black melonite steel barrel and a black melonite polymer frame. Its iconic island barrel design integrates four top-mounted gas ports to shift mass, dramatically reducing muzzle rise for flatter recoil and faster follow-up shots. The black melonite steel slide features serrations and an RMR optic-ready cut with an RMR footprint, complemented by a fixed front sight. Designed for duty, home defense, and competition, the pistol operates with a 15+1 capacity and is compatible with magazines for STK100, STK200, Glock 17, and Glock 19. The ergonomic grip is customizable via four interchangeable backstraps (small, medium, large, and extra-large). The package includes three magazines, an ammo case with a soft case inside, a guide rod, gun brush, Allen key, and cleaning rod.
