Oa Def Oa 9mm 5" 17-Round Night Sights Pistol

The OA Defense OA 9mm 5" 17-Round Night Sights Pistol is a purpose-built firearm designed for law enforcement, military, and civilian operators who demand reliability and precision in full-size carry and training applications. This full-size frame geometry accommodates shooters across hand sizes while maintaining controllability under sustained fire.

Engineered for both duty holster compatibility and competitive shooting, the OA Defense platform bridges the gap between service pistol ergonomics and modern tactical standards. The 5-inch barrel delivers consistent muzzle velocity and sight radius critical for accurate shot placement at tactical distances, while the magazine capacity of 17 rounds provides adequate ammunition reserves for extended engagement scenarios without requiring frequent magazine changes.

Integrated night sights enable target acquisition in low-light conditions—essential for defensive, law enforcement, and military operations where threats may occur outside daylight hours. The single-action trigger geometry ensures consistent break characteristics shot-to-shot, reducing reset travel and supporting rapid follow-up accuracy. This platform performs optimally for duty carry, defensive training, and sport shooting disciplines requiring reliable 9mm performance.
