Owners of the Derya DY9 Comp are drawn in by the feature list at the price point: a threaded compensated barrel, optics-ready cut, and Glock magazine compatibility in one package is uncommon at this tier. The compensator is noted as making a genuine difference in muzzle rise during rapid fire, which shooters appreciate at the range.

Glock magazine compatibility is a consistent positive for owners who already have a collection of Glock mags, removing the need to stock a separate caliber of magazines. The DY9 Comp's Truglo fiber sights get good marks for daytime visibility, though some owners swap them for aftermarket options in low-light environments.

Derya is a newer name in the US market and that brings some hesitation from buyers who prefer established brands. Customer service experience is reported as inconsistent. That said, owners who have had no issues tend to view the DY9 Comp as strong value for a feature-loaded 9mm pistol.
