Overview

ProMag occupies the budget tier of the PS90 magazine market at roughly $15. 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 for one-third the cost of factory FN. For any role where reliability matters, the FN OEM mag is the only safe choice.
