Promag Fnha14 20Rd 9Mm Fits Fn Reflex Blued Steel
The Promag FNHA14 20-round 9mm magazine is a high-capacity steel feed solution built for the FN Reflex pistol. If you run a Reflex and want to extend your on-range sessions or keep a deep magazine in rotation, this 20-round option trades the factory standard for serious round count between reloads. It's purpose-built for your platform—no adapter guessing or fitment questions.
Construction is straightforward and robust: a heat-treated steel body finished in black oxide, paired with an injection-molded follower and a heat-treated chrome silicone wire spring. That means the magazine is engineered to cycle reliably through thousands of rounds without losing its shape or spring performance. The materials are tough enough for both range work and defensive carry, though heavy use and proper cleaning will keep it running smoothly.
Promag built this one in the USA, so you're getting domestic manufacturing standards on a price-conscious alternative to OEM mags. The 20-round capacity makes it ideal for volume shooters, competition training, or anyone who wants a few extended magazines in their loadout without the premium price tag of factory options.
