SDS Arms RA9 Defense S Features The SDS Arms RA9 Defense S builds on the RA9 platform with a longer 4.75 inch barrel and a lightened slide all while retaining the modular RA9 Monoblock System that allows interchangeable and upgradeable grips and slides across the RA9 family. Weight-saving window cuts on the top and sides of the slide reduce overall mass without sacrificing durability and the QPQ Tenifer coating on both the slide and 4140 steel barrel resists corrosion and wear under hard use. The optics-ready slide includes an RMR adapter plate for direct mounting of a red dot giving shooters a fast precise sighting option. Ambidextrous slide stops make the pistol equally comfortable for right and left-handed shooters. A polymer frame with an integrated Picatinny rail supports lights and lasers while the polymer grip module keeps the overall unloaded weight to a manageable 1.81 pounds. The trigger system includes a steel guide rod and a drop-safe design for reliable consistent operation shot after shot. Fixed white dot sights provide a lower-third co-witness with mounted optics for quick target transitions. Shipping with two 17-round magazines a magazine loading tool and a cleaning kit the RA9 Defense S delivers a complete ready-to-carry package for shooters seeking a modular full-size 9mm pistol.
