The Derya DY9 is a semi-automatic pistol chambered in 9mm with a 3.86-inch barrel and a black finish. This variant ships with a 10-round magazine and is otherwise configured the same as the standard DY9: optics ready with two optic plates, Truglo fiber optic sights, four backstraps, and compatibility with Glock magazines.

Owners of the Derya DY9 in the 10-round configuration are generally buyers in restricted-capacity jurisdictions or those preferring a compliant setup. The Glock magazine compatibility is the same talking point that drives purchases of the standard variant, and the optics-ready platform is seen as good value at this price tier.

The four-backstrap grip system gets favorable comments from a range of hand sizes, and the Truglo fiber optic sights are a welcome addition over basic irons. Trigger feel is the most common criticism; some owners find it acceptable after several range sessions while others wish for a cleaner break out of the box.

On overall value, the 10-round DY9 fills a specific niche where capacity restrictions make the standard variant a non-option. Buyers in those markets tend to rate it positively given what the platform offers at its price point. Durability feedback is still accumulating, as the DY9 is a newer entry in a crowded segment.
