Oa Defense Mag Def 2311 15Rd

The OA Defense Mag Def 2311 15-round pistol magazine is built for shooters who need dependable ammunition storage for their OA Defense 2311 or Sig Sauer P320 platform. Whether you're at the range, in competition, or training for defensive readiness, this 9mm magazine combines proven steel construction with a durable polymer floorplate—the kind of no-nonsense design that works when it matters.

OA Defense magazines are engineered to feed reliably through thousands of rounds. The steel body resists wear and deformation under hard use, while the polymer base pad handles the impact of mag drops and repeated loading cycles. Fifteen rounds gives you solid capacity for practice sessions or duty carry without excessive bulk, and the straightforward design means nothing gets in the way of a clean reload.

If you run a P320 or the OA Defense 2311 platform, this magazine is worth having spares of—whether you're building a competition loadout, stocking up for range days, or maintaining a reliable backup supply. Straightforward, tough, and made to work.
