Derya DY9Z 9mm 3.50″ 15+1 Blue/Black
About this product
The Derya DY9Z 9mm 3.50″ 15+1 Blue/Black is a sub-compact striker-fired pistol designed for concealed carry that uses an RMSc optic cut and interchangeable backstraps for user customization. It’s built on a polymer frame with a corrosion-resistant Melonite slide finish. For context, it occupies the same general size class as the Glock 43X but carries one more round in its factory magazine.
What is the Derya DY9Z used for?
The Derya DY9Z is primarily a concealed carry weapon (CCW). Its short 3.50-inch barrel and 6.5-inch overall length make it easy to conceal in holsters from appendix to IWB positions, while the 15+1 capacity provides a practical balance of firepower and size for daily personal defense. The optic-ready slide also makes it a viable platform for low-profile red-dot training or defensive use without bulky slide adapters.
How does the Derya DY9Z compare to the SIG Sauer P365 XL?
The Derya DY9Z offers a higher initial magazine capacity at a lower price point than the SIG Sauer P365 XL. While the P365 XL comes factory standard with 12-round magazines (extendable to higher capacities at extra cost), the DY9Z ships with a 15-round flush-fit magazine, providing immediate capacity at its $245.99 MSRP, which is typically $150-$200 less than a new P365 XL. However, the SIG P365 platform has a far more extensive aftermarket ecosystem for triggers, holsters, and grip modules, which the Turkish-made DY9Z currently lacks.
What does it weigh and what are the dimensions?
The Derya DY9Z weighs 22 ounces (624 grams) unloaded and measures 6.5 inches in overall length. Its slide width is 1.06 inches, and the grip height from baseplate to beavertail is 4.8 inches, making it comparable in footprint to many micro-compact pistols. The 3.50-inch barrel contributes to the overall concealed profile, and with an unloaded weight under 1.5 lbs, it won’t cause undue holster sag during all-day carry.
Who is this NOT for?
This pistol is not for shooters seeking a suppressor host, a full-size duty/competition gun, or those who demand extensive aftermarket support. Its non-threaded 3.50-inch barrel rules out direct suppressor attachment, and its sight radius is too short for precise bullseye work beyond 25 yards. If you want a suppressor-ready platform, consider a rifle like the Stevens 334 chambered for .308. Furthermore, competitive shooters needing modularity will find more options with established brands like Glock or SIG.
What’s in the box?
You get the pistol, one 15-round steel magazine, two interchangeable polymer backstraps, a polymer cleaning rod, and a basic cable lock. The packaging includes a factory manual, but notably absent is a spare magazine or any hard-sided case—expect a cardboard box. For the price, the inclusion of only one magazine is an intentional cost-saving measure, so budget for at least one additional 15-round magazine ($30-$40) immediately.
Is the Derya DY9Z worth it at $245.99?
At $245.99, the DY9Z represents aggressive value for a striker-fired, optic-ready pistol with a 15-round capacity. You are primarily paying for the core mechanical package—slide, barrel, frame, and magazine—rather than accessories or brand prestige. If your priority is a reliable, no-frills defensive handgun with modern features and you accept a thinner aftermarket, it’s a compelling buy. However, if you plan to heavily customize your pistol with aftermarket triggers, slides, or barrel swaps, the investment is better directed toward a Glock or a more traditional platform like a Stevens 555 shotgun for sport shooting.

Pros & cons
What works
- 15+1 capacity in a sub-compact frame — holds one more round than the standard SIG P365 XL magazine.
- RMSc optic cut machined directly into the slide — eliminates the need for a $75-$150 adapter plate.
- Weighs 22 oz (624g) unloaded — approximately 2 oz lighter than a Glock 19 with similar capacity.
- Melonite slide finish provides a 72-hour salt-spray corrosion resistance rating.
Trade-offs
- Only one magazine included — requires an immediate $30-$40 additional purchase for a practical spare.
- Trigger pull measures 6.5 lbs with noticeable sponginess in the take-up — not suitable for precision work without aftermarket spring kits.
- Aftermarket holster and part support is limited — fewer than 10 major holster makers offer dedicated molds.

Frequently asked questions
- Is it compatible with Glock 43 holsters?
- No, the Derya DY9Z has a proprietary frame shape and trigger guard, so it will not fit standard Glock 43 or 43X holsters without modification. You need a holster specifically molded for the DY9Z, which are available from manufacturers like Vedder, We The People, and Alien Gear. I recommend verifying holster compatibility by checking the manufacturer’s model list before purchase.
- Does it fit RMSc footprint optics?
- Yes, the slide is cut to the RMSc (Shield RMSc) footprint, which directly accepts optics like the Shield RMSc, SIG Sauer ROMEOZero, and Holosun 407K/507K. The cut includes the recoil bosses but not the rear sight dovetail, so installing an optic requires removing the factory rear sight. Torque the optic mounting screws to 12-15 in-lbs using thread locker to prevent loss during firing.
- How long does shipping take?
- For in-stock items, Ironclad Armory processes and ships within 1-2 business days via FedEx or UPS Ground. Transit time is typically 3-7 business days depending on your location, but you will receive a tracking number within 24 hours of the label being created. For FFL items, allow an extra 24-48 hours for the dealer verification process before the carrier picks up.
- Can I return it if it doesn't fit my hand?
- No, Ironclad Armory does not accept returns on firearms, ammunition, or firearm parts for fit or preference reasons due to federal regulations. All firearm sales are final once the 4473 transfer is completed at your FFL. We strongly recommend handling the model at a local dealer or range before purchasing to confirm ergonomics and feel with the included backstraps.
- Does this work with Beretta 92 magazines?
- Absolutely not. The Derya DY9Z uses proprietary, double-stack 9mm steel magazines with a unique feed angle and magazine catch cut. Attempting to force-fit a Beretta 92, Glock, or SIG magazine will cause feed failures and potentially damage the magazine well. Only use Derya DY9Z-specific 15-round magazines, available directly from Ironclad Armory or authorized parts distributors.
