Zev Technologies OZ9 Compact 9mm Luger 4in Black Pistol - 15+1 Rounds - ZEV Technologies first complete pistol, built entirely from the ground up, is now available in a compact model. All the same great features as the standard sized O.Z-9, the compact blurs the line between personal defense, concealed carry and a duty pistol. The slimmed-down PRO magwell enhances grip comfort while minimizing printing while carrying concealed. The O.Z-9 was designed and created for balance. It's 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.
