For shooters who demand reliable feeding and durable construction in a spare magazine, the right choice balances metal strength with polymer resilience. Whether you carry a SIG P220 for duty, competition, or range drills, a well-built magazine is a foundational upgrade that affects function and confidence at the grip.
PROMAG SIG P220 is an 8-round magazine built specifically for .45 ACP pistols. 
Design and materials that matter
This PROMAG SIG P220 magazine pairs heat-treated blued steel body construction with a follower lockplate and baseplate to deliver long-term wear resistance. The follower and baseplate are molded from a proprietary DuPont Zytel-based black polymer, providing a low-friction interface for reliable round stacking and smooth insertion. For shooters concerned with corrosion and feed-lip deformation, the blued steel body offers a balance of hardness and finish at an affordable price point ($19.79).
Why .45 ACP compatibility is relevant
The PROMAG SIG P220 is chambered for .45 ACP platforms, making it appropriate for those who appreciate the cartridge’s stopping power and proven performance in defensive and duty roles. The 8-round capacity matches classic P220 ergonomics, keeping flush fitment while maintaining a positive grip profile for repeatable reloads. For range users and instructors, a compact 8-round magazine also simplifies carry and training logistics.
Fit, function, and maintenance
Because this magazine is offered in various models to suit different P220 variants, confirm slide and frame compatibility before purchase. The follower lockplate reduces follower tilt and feeding issues common with cheaper magazines, and the DuPont Zytel components resist impact and environmental stress. Routine cleaning of the blued steel body and polymer internals will preserve reliable operation.
