The Derya DY9 is a striker-fired 9 mm pistol with customizable ergonomics thanks to four interchangeable backstraps. Its optics-ready, bronze-Cerakoted slide sits atop a lightweight polymer frame with an accessory rail, while a hardened, nitride-coated alloy-steel barrel and fiber-optic 3-dot sights enhance reliability and target acquisition.
I like this pistol, but was disappointed when I loaded different types of Hornady defense rounds. It wouldn't cycle any of them. Cycled all types of ammo as long as it was round ball. Not sure if it's the magazine, the ramp, or what. I'll purchase other brands and see what happens. Overall, I'm happy with the pistol. Ergonomics, accuracy, and recoil are all very nice.
