The Rock Island DY915 is a 15-round 9mm magazine purpose-built for Rock Island Armscor's DY9 and STK200 handguns. If you're running either of these platforms—whether for home defense, range work, or duty carry—this OEM magazine ensures reliable feeding and consistent performance with your gun. Constructed from durable black polymer, it's engineered to the same tolerances as your firearm, so you get the fit and function Armscor designed in from the start.
Magazine reliability is non-negotiable. Cheap aftermarket mags can cause feeding hiccups, light primer strikes, or worse. The DY915 is the factory-standard choice, meaning it's been tested in your specific gun and proven to work. The 15-round capacity balances magazine-fed capacity with practical handling and concealment, making it a solid choice for both duty and personal defense configurations.
If you own a DY9 or STK200, having multiple magazines on hand is smart practice. Buy spares now so you've got backups for the range, and a full rotation ready to go when you need it most. Spare magazines wear out over time—springs weaken, followers get nicked—so rotating fresh ones into your carry or duty rotation keeps your gun running right.
