"The IWI Masada Tactical Optics-Ready Semi-Auto Pistol is a combat-ready, striker-fired handgun built for the modern battlefield. The Masada's frame is made from high-strength, impact-resistant, fiberglass-reinforced polymer that's built to withstand torture-testing and military use in the harshest environments. The Masada comes with a 4.6"" low-profile, threaded barrel that helps reduce felt recoil and will gladly accept a suppressor. Fully ambidextrous controls and enhanced ergonomics provide natural control and instinctive pointing. You get 3 interchangeable backstraps to fit your hand. The Masada is an optics-ready pistol designed to be used with the Trijicon RMR, Vortex Venom, Leupold DeltaPoint Pro, and SIG SAUER ROMEO1 optics. Respective adapter plates are included. Completing the package is IWI's 6-lb. trigger with a clean, crisp break and positive reset. Includes 2 magazines, 3 backstraps, and 4 optics plates.
