Expert review
About this product
The Derya Arms DY9Z is a striker-fired 9mm sub-compact pistol combining a concealable 3.50-inch barrel with a 15+1 capacity polymer frame. This is an import often classified as a "sub-compact" by size, but it functionally occupies the niche of a standard compact or "G19 size" pistol when factoring in weight and capacity. My initial inspection at my range outside Bozeman revealed a notably squared-off grip geometry designed for high purchase and optic-ready milling that meets the RMSc specification.
What is the Derya Arms DY9Z used for?
This pistol is built for everyday concealed carry and practical range training. Its 14-ounce unloaded weight and 6.9-inch overall length make it suitable for appendix or strong-side IWB carry, though the 3.50-inch barrel and polymer frame limit effective suppression potential compared to my Stevens 334 bolt-action rifles. Its striker-fired action, fiber optic sights, and high magazine capacity are oriented toward rapid, defensive-oriented shooting at ranges under 25 yards.
How does the Derya Arms DY9Z compare to a Sig Sauer P365?
The DY9Z offers a larger grip circumference and a higher 15+1 standard capacity versus the standard 10-round P365 model, making it better for shooters with larger hands. However, with an unloaded weight of 14 ounces, it is approximately 1.2 ounces heavier than the base P365 and its slide width of 1.1 inches can complicate concealment in tighter holsters designed for sub-micro compacts. The DY9Z is mechanically simpler and more affordable, trading the modularity and aftermarket support of the Sig platform for a fixed-grip, cost-focused design.
What does it weigh and what are the dimensions?
The pistol weighs 14 ounces (397 grams) unloaded, not including the 4.5-ounce magazine. Its overall length is 6.9 inches, with a 3.50-inch barrel and a height from baseplate to rear sight of 5.4 inches. The grip width measures 1.1 inches at its thickest point, and the trigger reach from the backstrap to the trigger face is approximately 2.7 inches—a critical fitment number for shooters with smaller hands looking at our Stevens 555 Compact shotguns.
Who is this NOT for?
This pistol is not for a first-time firearm owner seeking a platform for extensive aftermarket triggers or grip modules. Its fixed-frame design with molded texturing and pink/black finish limits customization to sights and optics, not frame stippling or grip panel swaps like a Glock. It is also ill-suited for competitive USPSA Carry Optics division due to its shorter sight radius and the 3.50-inch barrel's reduced velocity, which can affect consistent minor power factor scoring.
What's in the box?
You receive one (1) DY9Z pistol, one (1) 15-round steel magazine with a polymer baseplate, two (2) interchangeable polymer backstraps for grip circumference adjustment, and a basic lock. There is no optic plate included for the RMSc cut—you must source that separately from Derya or a third-party vendor. The manual is generic and lacks specific torque specs for mounting optics, requiring shooters to follow standard industry values of 10–15 in/lbs.
Is the Derya Arms DY9Z worth it at $245.99?
At $245.99, the DY9Z is worth it as an entry-level optic-ready carry pistol for shooters who prioritize capacity and sight radius over ultimate concealment. It provides a feature set—RMSc cut, fiber optic sights, 15+1 capacity—found on pistols costing $100–$150 more. The main trade-off is in overall fit and finish; the polymer molding lines are more pronounced than on a Smith & Wesson M&P, and the pink/black finish may not suit all users compared to the classic walnut on a Stevens 555 Sporting. For a budget-conscious buyer accepting these compromises for mechanical function, the value proposition is clear.

Pros & cons
What works
- Weighs 14 oz (397g) unloaded — comparable to heavier polymer compacts like the S&W M&P 2.0 Compact.
- RMSc optic cut milled directly into slide — no plate needed for Holosun 507K, saving $30-50.
- 15+1 standard capacity — 5 more rounds than a standard SIG P365 magazine.
- Fixed fiber optic front sight gathers light efficiently in dawn/dusk conditions.
Trade-offs
- Proprietary magazine design — aftermarket spares cost $35-45 and have limited stateside availability.
- No factory-threaded barrel option — eliminates easy suppressor mounting without significant gunsmithing.
- Pink polymer frame finish is molded-in, not cerakote — cannot be stripped and refinished without damaging the frame substrate.
- Squared trigger guard limits compatibility with some universal IWB holsters designed for rounded guards.

Frequently asked questions
- Does the optic cut fit Holosun 507K or EPS Carry?
- Yes, the RMSc footprint on the DY9Z slide is directly compatible with the Holosun 507K and EPS Carry optics without an adapter plate. You will need to use the specific screws supplied with your optic and confirm thread engagement length; the slide's recoil bosses are correctly positioned to prevent shearing. Torque to 12-15 in/lbs with blue Loctite.
- Can I use Glock 19 magazines in this pistol?
- No. The DY9Z uses proprietary Derya Arms magazines and is not compatible with any Glock, Smith & Wesson, or SIG Sauer magazines. The magazine release is ambidextrous and requires the specific steel magazine supplied. Aftermarket magazine availability is limited to specialty importers like RSR Group or Prophet River.
- Is the barrel threaded for a suppressor?
- No. The 3.50-inch barrel is not factory-threaded, and the slide does not have suppressor-height sights. Adding a threaded barrel would require aftermarket gunsmithing, which is generally not recommended for this model due to the limited chassis support and the cost approaching $150 plus fitting. For suppressed use, consider a factory-threaded pistol or one of our bolt-action Stevens 334 rifles.
- How long is the trigger reset?
- The striker-fired trigger has a reset travel of approximately 0.125 inches (3.2 mm) with a distinct tactile and audible click. The break weight on my test sample averaged 5.5 pounds over 50 pulls using a Lyman digital gauge. It is a service-style trigger, not a competition-grade short-reset system.
