ZEV Technologies first complete 9mm pistol with everything built entirely from the ground up by ZEV. The O.Z-9 was designed and created for balance. Its one of the first things you notice when holding this pistol. Balance equates to what every shooter is looking for; a more controllable pistol with less felt recoil, less muzzle flip and faster, more accurate follow-up shots. At the heart of the O.Z-9 is our patent pending steel receiver. This solid steel frame runs the length of the entire pistol allowing the locking block to be fully integrated.
