ProMag Polymer Pistol Magazine, FN PS-90/P-90, 5.7x28mm, 50-Round, Clear, FNH-A3-50RD
ProMag occupies the budget tier of the PS90 magazine market. Reputation is mixed: some shooters report years of reliable service, others see early feed-lip cracking and follower issues. The right move is to buy a small number, function-test thoroughly, and decide whether to stockpile based on personal results.
For casual range plinking on a tight budget, ProMag delivers 50 rounds of horizontal feed below factory FN pricing. For any role where reliability matters, the FN OEM mag remains the safer choice.
