The ZEV O.Z-9 Combat features all the same functionality and modularity of the O.Z-9 in a configuration optimized for durability. Built with ZEV's windowless Citadel slide, PRO match barrel and PRO Curved Face Trigger, the O.Z-9 Combat is tailored to meet the stringent requirements of the discerning professional user. Also, our patented steel receiver, the extended rails in the steel receiver help provide more than double the surface area of contact to the slide. A single take-down pin conveniently located at the front of the trigger guard locks the removable grip to the steel receiver. The trigger is housed in the steel receiver allowing for future grip upgrades without completely breaking down the pistol. Our improved grips have steeper angles, and forward hand position keeping the muzzle down, and pointing straighter. Includes two Magpul PMAG's.
