OA Defense 2311 Compact Pro 9mm | 4.25 in | 15+1

The OA Defense 2311 Compact Pro is a compact, optic-ready semi-automatic pistol designed for everyday carry and personal defense. It combines a ported DLC-coated barrel, a contoured serrated slide, and a tuned trigger system for consistent performance in a small package. The Compact Pro is fully ambidextrous and ships with multiple magazines and a 7075 aluminum magwell for faster reloads. For an optic under $1,000 that pairs well with this platform, consider a compact red-dot such as the Holosun 507K series for low-profile footprint and reliable dot performance.
