Rugged DuPont® Zytel® Polymer Construction
Instead of traditional steel, ProMag uses a proprietary DuPont® Zytel®-based polymer for the magazine body. This advanced polymer is well known for its toughness and impact resistance. drummagazines.com+3promagindustries.com+3GunMag Warehouse+3
Durable polymer shell resists dings, dents, and corrosion
Lightweight design keeps overall pistol weight manageable even when fully loaded
Black finish blends cleanly with the lines and style of the MPA 30 Defender
Polymer construction also helps the mag shrug off hard range use, drops, and environmental exposure better than many budget metal mags.
Smooth Feeding: Injection-Molded Follower & Chrome Silicone Spring
Reliable feeding is essential in any high-capacity pistol magazine, especially at 32 rounds. ProMag builds the MPA-A1 internals for consistent, repeatable performance:
This combination helps reduce common magazine issues such as nose dives, sluggish feeding, or premature spring fatigue, giving you more confidence during rapid fire or extended range sessions.
High-Capacity Advantage – Fewer Reloads, More Time on Target
