Promag Sig P320 9mm 50rd Drum Black

The Promag Sig P320 9mm 50rd Drum Black is a high-capacity magazine system designed specifically for the Sig Sauer P320 platform. This drum magazine allows shooters to enjoy extended firing cycles on the range and during training, minimizing the need for frequent reloads and enhancing the shooting experience. Its 50-round capacity provides a significant increase over standard P320 magazines, which typically hold 17 or 21 rounds.

Constructed from durable black polymer, this magazine balances weight considerations with the need for reliability during extended use. The design is tailored to the P320's feed geometry and spring tension, ensuring dependable feeding across various P320 configurations. Users should be aware that drum magazines can be more complex in terms of spring mechanics and feed lips, necessitating regular inspection and maintenance.

This magazine is ideal for operators engaged in high-volume training, competitive shooters, and defensive practitioners seeking enhanced capacity for home defense. Its compatibility with the P320 platform—including standard and compact variants—makes it a valuable upgrade for existing P320 users without requiring any platform changes. The 50-round configuration allows for reduced administrative handling time on static ranges and supports longer dry-fire and live-fire drill cycles.
