The Derya Arms DY9 Comp is the upgraded, compensated version of Derya's flagship DY9 pistol, assembled right here in the United States at their Jacksonville, Florida facility. It's striker-fired, chambered in 9mm, and ships ready for action with 15+1 capacity. The defining feature is the 4.64-inch threaded honeycomb stainless steel barrel with a factory-attached compensator. The comp uses upward-directed gas ports to reduce muzzle flip by roughly 25%, which translates to noticeably flatter shooting and quicker target reacquisition, especially during rapid fire. The honeycomb pattern on the barrel also helps with heat dissipation and shaves a little weight off the front end.
The slide is forged steel with a Black Melonite finish, ported to reduce weight, and cut for optics right out of the box. Two universal optic plates are included, compatible with red dots from Trijicon, Vortex, Truglo, Docter, Meopta, and Insight. Truglo fiber optic sights come installed, with a red front and green rear, so you have usable irons whether you mount a red dot or not. The loaded chamber indicator sits in the optic cut area but stays visible even with a plate installed.
Grip ergonomics are a strong point here. The polymer frame ships with four interchangeable backstraps in sizes S, M, L, and XL, so finding the right fit regardless of hand size is straightforward. The DY9 Comp also runs Glock 17 and Glock 19 compatible magazines, which keeps your options wide open for adding spares or using mags you may already own. The 1/2×28 threaded barrel makes swapping in a suppressor quick and easy when the comp is removed.
Derya backs the DY9 Comp with a limited lifetime warranty to the original purchaser. It's a well-rounded pistol that punches well above what most people expect at this price point, and the factory comp is the kind of feature you'd normally have to spend extra money to add yourself.
Yes, the compensator comes factory-installed on the threaded honeycomb stainless steel barrel. You don't have to source or purchase it separately. The barrel is threaded at 1/2×28, so if you want to swap to a suppressor down the road, you just remove the comp and thread on your can.
The DY9 Comp ships with two universal optic plates that cover footprints from Trijicon, Vortex, Truglo, Docter, Meopta, and Insight. That covers a wide range of popular red dots. Torque the optic plate screws to 12-16 inch-pounds for a secure fit.
The DY9 Comp is compatible with magazines for the Glock 17 and Glock 19, as well as the Palmetto State Armory Dagger. Most standard Glock 19 and Glock 17 pattern mags will work, though Derya notes that compatibility with all aftermarket magazines isn't guaranteed. Extended 30+ round Glock pattern magazines also fit.
According to Derya, the factory compensator reduces muzzle rise by approximately 25% by directing propellant gases upward through the comp's ports. In real-world shooting, this makes follow-up shots noticeably faster and flatter compared to a non-compensated barrel, especially during rapid fire strings.
Yes. The MPN ending in 'US' indicates this is a US-manufactured variant, built at Derya's facility in Jacksonville, Florida. Derya began US manufacturing to expand their lineup and better serve the American market.
Many Glock 19 holsters will physically fit the DY9 platform, but the added compensator on the DY9 Comp extends the overall length to 7.52 inches, which means a standard Glock 19 holster likely will not accommodate it. You'll want to look for a holster specifically designed for the DY9 Comp or one that fits compensated pistols.
