MASADA’s frame is made of high strength, impact resistant fiberglass reinforced polymers. Like all IWI firearms, it is built to withstand and endure all types of military use and abuse in extremely harsh environmental conditions. MASADA utilizes a modular serialized high grade steel trigger mechanism housing that can be easily removed, allowing simple and easy disassembly and maintenance. MASADA’s trigger is designed to enhance the shooter’s accuracy and safety. The MASADA trigger has a 6 lb trigger pull. with a clean and crisp break and a positive reset. Featuring a built-in trigger safety, the pistol will not fire unless the trigger is pulled. MASADA is an optics-ready platform and is designed to be used with the Trijicon RMR, Vortex Venom, Leupold Delta Point Pro, and Sig Romeo1 optics. Respective adapter plates and screws for each of these optics allow the optic to mount directly to Masada’s slide. Mounting any optic other than those listed here will risk damaging the firearm.
