Key features
- Factory compensator — reduces muzzle rise and felt recoil by about 30% compared to a standard compact 9mm, letting you keep the dot on target for faster follow-up shots.
- Optic-ready slide — comes with two optic plates so you can mount your favorite red dot without milling or adapter costs.
- Threaded stainless steel barrel — 4.64 inches with 1/2×28 threads, ready for a suppressor or your own muzzle device if you swap the comp.
- Interchangeable backstraps — three sizes included so you can dial in the grip angle and palm swell for your hand size.
- Black Melonite finish — resists holster wear, sweat, and corrosion better than standard bluing or nitride; holds up in humid carry conditions.
Who it’s for
This is for the daily carrier who wants compensator performance out of the box — no waiting on a gunsmith, no guessing if parts fit. It’s for the shooter who runs red dots on their carry guns and wants a factory-ready slide. And it’s for anyone who wants a reliable, American-made 9mm that doesn’t cost Agency Arms money.
Pros / Cons
- Pro: Factory comp included — saves you $100+ and the headache of thread locker and timing shims.
- Pro: Optic plates for three common footprints (RMR, Holosun K, Doctor) mean you can mount most micro dots right away.
- Con: The trigger pull is a bit heavier than aftermarket triggers — around 6.5 lbs out of the box. It’s crisp but not competition-grade. If you want a lighter break, budget for a trigger swap.

FAQ
Does the Derya DY9 COMP come with a hard case?
Yes. It includes a hard plastic case, one 15-round magazine, the compensator (pre-installed), and two optic plates. You can store the extra plate and the manual inside the case.
Can I run this gun without the compensator?
Yes. The comp is attached via the 1/2×28 threads. You can remove it and run the bare threaded barrel or install a suppressor. Just be aware the barrel extends 0.6″ past the slide, so holster fit may change.
What red dots fit the included optic plates?
The two plates cover: RMR/SRO footprint, Holosun 407K/507K footprint, and Doctor/Noblex footprint. Trijicon, Holosun, Swampfox, and Vortex micro dots will mount with the right plate.
Is the DY9 COMP reliable with hollow points?
Per Derya USA specs, the pistol is tested with 124-grain FMJ and JHP loads. Users report it feeds Federal HST, Speer Gold Dot, and Hornady Critical Duty without issues. The comp doesn’t affect reliability with standard-pressure defensive ammo.
