Extended-capacity magazines can transform how you prepare for range sessions, competitive shooting, or duty carry by reducing reload frequency while maintaining reliable function under stress. For shooters who depend on consistent feeding and durable construction, choosing the right magazine is as important as the firearm itself.

PROMAG FN FIVE-SEVEN

Shop this product to see current stock and ordering options. This magazine is built specifically for the FiveSeven pistol in 5.7x28mm and offers a 30-round capacity that changes how you approach training and high-round-count drills.

Design and Construction

The PROMAG FN FIVE-SEVEN uses an injection-molded housing and follower constructed from impact-resistant, glass-filled nylon polymer. That material choice balances toughness with weight savings, resisting cracking under repeated insertion and removal. The follower design promotes consistent round positioning to minimize misfeeds.

Spring and Feed Reliability

The spring is precision wound from heat-treated Chromesilicon wire, a material known for resilience and long-term spring memory. In practice, this translates to reliable feeding throughout the magazine’s life cycle — a critical attribute for extended-capacity magazines where spring fatigue can be a limiting factor.

Caliber Considerations: 5.7x28mm

Chambered for the 5.7x28mm cartridge, this magazine supports the unique ballistic profile of that round: high velocity, flat trajectory, and low recoil compared to many pistol calibers. The combination of a 30-round capacity with the 5.7’s controllability is well-suited for fast follow-up shots, target transitions, and drills that emphasize speed and accuracy.
