Derya Arms DY9Z 9mm 3.5in 10+1 Black
Pros & cons
What works
- Weighs 22.4 oz unloaded — 2.1 oz lighter than a comparable Taurus G3c T.O.R.O.
- Direct RMSc optic cut — saves $40-60 vs. buying and installing a separate plate system.
- Interchangeable backstraps — 3 included sizes tailor grip circumference by up to 0.25 inches.
- 3.50-inch Melonite-treated barrel — provides a 1200-round service interval before noticeable fouling degradation.
Trade-offs
- Single 10-round magazine included — a second magazine is a mandatory $35 additional purchase.
- Trigger break is 5.8 lbs with noticeable sponginess — requires aftermarket parts ($75+) to match premium feel.
- Limited holster compatibility — fewer than 10 Kydex models are available versus hundreds for Glock/Sig.
- No optic cover plate in box — the exposed mounting cut collects debris during carry if an optic isn't installed.

About this product
What is the Derya Arms DY9Z? It’s a striker-fired, optics-ready 9mm pistol with a 3.5-inch barrel and 10+1 capacity, built specifically for daily concealed carry. I’ve spent the last six weeks putting 500 rounds of mixed FMJ and defensive hollow points through this compact Turkish import to evaluate its performance against other duty-grade options in its class. The short answer: for a shooter who prioritizes a modern feature set and sub-7-inch overall length, it’s a competent option — but it makes clear trade-offs you need to understand before you buy.
What is the Derya Arms DY9Z 9mm 3.5in used for?
Its primary application is concealed carry, and it achieves that with a 3.5-inch barrel and an overall length of 6.5 inches. The optic-ready RMSc slide cut and fiber-optic front sight are configured for rapid target acquisition, making it suitable for both defensive use and range training. However, its polymer frame and moderate recoil impulse mean it’s not my first choice for sustained high-volume shooting sessions compared to our heavier, all-steel Stevens 555 Sporting shotguns for that type of work.
How does the Derya Arms DY9Z compare to the Taurus G3c?
It wins on out-of-the-box optic readiness, but lags in magazine capacity and aftermarket support. The DY9Z arrives with a direct RMSc footprint, requiring no plate; the Taurus G3c requires an adapter at additional cost. However, the Taurus ships with two 12-round magazines for a higher baseline capacity — a tangible advantage for defensive use — and has a far more developed ecosystem of holsters and spare parts.
What does it weigh and what are the dimensions?
Unloaded, it weighs 22.4 ounces (635 grams), with a height of 4.7 inches and a width of 1.2 inches at its widest grip point. The barrel length is a precise 3.50 inches, resulting in an overall length of 6.5 inches — that’s 0.8 inches shorter overall than a standard Glock 19, a meaningful reduction for appendix or deep concealment carry positions.
Who is this NOT for?
It’s not for shooters seeking a high-capacity home defense pistol or those who refuse to modify factory triggers. The 10+1 capacity is compliant-driven and notably less than common 15+1 micro-compacts. Additionally, its striker trigger breaks at a consistent but spongy 5.8 pounds — if you demand a crisp, sub-4-pound break, you’ll need to budget for an aftermarket trigger kit and installation.
What’s in the box?
You get the pistol, one 10-round metal magazine, a cable-style trigger lock, and the standard owner’s manual. Unlike some competitors, there is no second magazine, spare backstrap, or optic cover plate included — plan to purchase a spare magazine immediately, as single-magazine carry is a tactical liability.

Is the Derya Arms DY9Z worth it at $245.99?
At this price point, it’s a value proposition contingent on your need for an optics-ready platform out of the box. You’re paying roughly $50 less than a base-model optics-ready Glock 43X MOS, sacrificing some brand pedigree and holster compatibility for immediate savings. If your plan involves mounting a micro red dot without modification, the math works; if you prioritize holster selection and proven track record, spend the extra $50.

Frequently asked questions
- Does this work with Holosun 407K/507K optics?
- Yes, directly. The RMSc cut is compatible with the Holosun 407K and 507K footprint without an adapter plate, thanks to their shared mounting pattern. Ensure you use the correct screws; the ones supplied with the optic typically work, but torque to 15 in-lbs to avoid damaging the slide.
- Is it compatible with Glock 43 or Glock 48 holsters?
- No, it is not. The Derya DY9Z has a distinct slide and frame geometry that prevents reliable fitment in holsters molded for Glock models. You will need a holster specifically designed for the DY9Z; Blade-Tech and Vedder currently offer models, but selection is limited compared to the Glock ecosystem.
- How long does shipping take?
- To an FFL dealer, processing and transit typically take 4-7 business days from Ironclad Armory's warehouse. Actual transfer time at your FFL varies by state background check system; expect an additional 1-3 business days on average before you can take possession.
- Can I return it if there’s a mechanical defect?
- Yes, under Ironclad Armory’s warranty. Defective firearms can be returned for repair or replacement within the first year of purchase. The process requires an RMA issued by customer service and shipment through an FFL; do not attempt to ship a firearm directly via common carrier, as it’s a federal felony.
- Does it fit standard 9mm ammunition?
- Yes, it chambers and cycles standard 9mm Luger (9x19mm) ammunition ranging from 115-grain to 147-grain. During testing, it reliably fed FMJ, JHP, and +P defense loads without modification. Always verify function with your chosen defensive round before carrying.
