ProMag FNH PS90/P90 Magazine 5.7x28mm Clear Polymer 50/rd

The ProMag FNH PS90/P90 Magazine 5.7x28mm Clear Polymer 50/rd is purpose-built for operators who demand extended capacity without sacrificing reload speed or ergonomics. Chambered in 5.7x28mm NATO, this 50-round polymer magazine serves military and law enforcement professionals running FN Herstal P90 or PS90 platforms. The clear polymer construction allows rapid round-count verification in the field—a critical advantage during tactical operations or extended training cycles where ammunition accountability matters.

Manufactured by ProMag Mfg. Inc., this magazine leverages reinforced polymer engineering to maintain feed reliability across repeated duty cycles. The 50-round capacity positions the magazine well above standard 30-round alternatives, extending trigger time between reloads—particularly valuable in scenario-based training or sustained defensive applications. The translucent design reduces operational friction by eliminating the need to physically drop the magazine to confirm ammunition levels, saving precious seconds during magazine rotation or tactical transitions. Lightweight at 0.5 lbs, the magazine does not introduce excessive weight to your kit when loaded with 5.7x28mm rounds, ensuring consistent handling characteristics across your primary and secondary magazines.

This magazine is compatible exclusively with FN P90 and PS90 rifles in 5.7x28mm configuration, making it essential for any operator relying on this platform for duty, home defense, or specialized training. The 50-round format proves ideal for shooters transitioning from carbine or rifle-length training who want to replicate high-volume fire without frequent magazine changes. Law enforcement and military armories benefit from the transparent design during inventory management and round-count audits. Compact dimensions (3.9 x 2.3 x 16.15 inches) ensure the magazine stacks efficiently in magazine carriers, tactical vests, or duty rigs without creating unnecessary bulk or weight distribution issues.
