Derya DY9Z 9mm 3.50″ 15+1 Black
Pros & cons
What works
- RMSc optic cut pre-milled — saves $150-$200 over aftermarket milling
- 23 oz unloaded weight — 4.3 oz heavier than a Glock 43X but carries 5 more rounds
- 15+1 capacity — exceeds most micro-compacts by 3-4 rounds in same footprint
- Melonite finish on slide — provides 72-hour salt-spray corrosion resistance per ASTM B117
Trade-offs
- Limited holster compatibility — requires specific molds from smaller manufacturers
- Non-threaded barrel — no suppressor attachment without $120+ aftermarket barrel swap
- Minimal aftermarket support — trigger upgrades, slide releases, and mag extensions are scarce
- Sights are not suppressor-height — will be partially obscured by most micro red dots

About this product
What is the Derya DY9Z 9mm 3.50" 15+1 Black? It's a Turkish-made, striker-fired subcompact pistol built primarily for concealed carry duty, with an optics-ready footprint and 15+1 capacity in a 3.5-inch-barreled polymer frame. The platform represents a deliberate move toward modern feature integration—the RMSc slide cut, Melonite surface treatment, and fiber-optic sights aren't afterthoughts. For shooters navigating the proliferation of micro-compacts, the DY9Z offers a notable capacity advantage without stepping into midsize dimensions.
What is the Derya DY9Z used for?
The DY9Z is engineered for daily concealed carry, with its 6.5-inch overall length and 23-ounce unloaded weight providing a concealable yet shootable platform for defensive use. The 3.5-inch barrel length balances velocity retention with holster compatibility, while the 15-round magazine capacity exceeds most micro-compacts by 3-4 rounds. This makes it suitable for range training, home defense backup, and all-day appendix or strong-side carry roles where capacity is prioritized over absolute minimalism.
How does the Derya DY9Z compare to a Stevens 334 rifle?
The DY9Z serves a completely different tactical role than a long gun like the Stevens 334 rifle—it’s a close-quarters defensive tool, not a precision or hunting platform. Where the Stevens 334 in .308 Win delivers energy at 200+ yards, the DY9Z’s 9mm cartridge is optimized for defensive distances under 25 yards. The DY9Z’s polymer frame and 23-ounce weight make it concealable, while the Stevens 334’s bolt action and 20-inch barrel provide sustained accuracy. The Stevens is better for hunting or deliberate marksmanship; the Derya is better for personal defense and concealed carry.
What does it weigh and what are the dimensions?
The DY9Z weighs 23 ounces unloaded and measures 6.5 inches in overall length, 4.9 inches in height, and 1.1 inches in width. The 3.50-inch cold-hammer-forged barrel contributes roughly 11 ounces to that total weight, while the polymer frame with two interchangeable backstraps keeps bulk manageable. For comparison, a Glock 43X measures 6.5 inches long and 1.1 inches wide but weighs about 18.7 ounces—the DY9Z trades 4.3 ounces for 5 additional rounds of capacity in the same footprint.
Who is this NOT for?
The DY9Z isn’t for shooters who demand extensive aftermarket support or domestic manufacturer provenance. As a Turkish import, holster compatibility and spare-parts availability won’t match Glock or SIG’s ecosystem. It’s also not ideal for suppressors due to the non-threaded barrel, unlike some purpose-built compact hosts. Finally, those prioritizing absolute minimal weight for deep concealment should look at micro-9s like the SIG P365, which save 5-7 ounces at the cost of 3-4 rounds.
What’s in the box?
You receive one metal 15-round magazine, two interchangeable backstraps (small and medium), a basic plastic case, and a user manual. The magazine uses a steel body with an anti-tilt follower and a polymer baseplate—it's serviceable but not premium. There’s no thread protector, extra optic plates, or cleaning kit included. For a similar price point, the Stevens 555 Sporting shotgun includes five choke tubes; the DY9Z’s packaging is strictly utilitarian.
Is the Derya DY9Z worth it at $245.99?
At $245.99, the DY9Z is competitively priced if you value optics readiness and above-standard capacity in a subcompact. You’re getting an RMSc-cut slide, fiber-optic sights, and a 15+1 configuration for roughly $100 less than a base Glock 43X MOS. The trade-off is limited holster compatibility and unknown long-term parts support. If you need a dedicated carry gun with modern features and don’t mind sourcing holsters from smaller manufacturers, it’s a valid option. If you prioritize resale value or domestic supply chains, spend the extra $100-$150 on an established brand.

Frequently asked questions
- Is it compatible with Holosun 407K/507K optics?
- No, the DY9Z’s RMSc cut is not directly compatible with the Holosun 407K/507K footprint without an adapter plate. The RMSc pattern lacks the rear recoil lugs required for the Holosun optics. You’ll need a third-party adapter plate from brands like CHPWS or Calculated Kinetics, which adds approximately 0.12 inches of height and costs $40-$60.
- Does it fit Glock 19 holsters?
- No, the DY9Z’s frame dimensions and trigger guard geometry differ from the Glock 19. The slide width is 1.1 inches versus the G19’s 1.0 inches, and the frame contours are not interchangeable. You’ll need a holster specifically molded for the DY9Z—options are available from Vedder, Alien Gear, and smaller custom shops, but they’re not as ubiquitous as Glock holsters.
- How long does shipping take?
- For most online orders through Ironclad Armory, shipping via UPS or FedEx takes 3-5 business days after FFL verification. Firearms require shipment to a licensed dealer for transfer, which adds 1-2 days for FFL paperwork processing. Express shipping options are available for an additional $25-$35, cutting transit time to 2 business days.
- Can I return it if it doesn't fit my hand?
- No, firearms are non-returnable under federal law once transferred through an FFL. You can inspect the firearm at your FFL before completing the 4473 form—if you decline transfer at that point, Ironclad Armory will refund the purchase price minus a 15% restocking fee and return shipping. Always check grip ergonomics with a rental or display model before buying.
- Does this work with suppressor-height sights?
- The factory fiber-optic sights are not suppressor-height and will likely be obscured by most micro red dots if mounted. Aftermarket suppressor-height sights require a gunsmith to fit them due to the DY9Z’s proprietary dovetail cut. Dawson Precision and Night Fision offer compatible sights starting at $80, but installation adds another $50-$75 in gunsmithing fees.
