ProMag FNHA10 5.7x28mm 10rd Blued Steel Magazine - Fits FN Five-seveN USG

The ProMag FNHA10 is a 10-round replacement magazine engineered for the FN Five-seveN USG pistol chambered in 5.7x28mm. Built as a reliable aftermarket option for one of the most distinctive semi-auto pistols on the market, this magazine keeps your Five-seveN fed and ready at the range or on the bench.

Constructed from blued steel for long service life and confident feeding, the FNHA10 mirrors the OEM profile of the factory 10-round magazine so it seats cleanly in the pistol's magazine well. The 10-round capacity makes it a compliant spare or backup for owners in jurisdictions that restrict higher-capacity Five-seveN magazines, and it is an ideal direct replacement for a worn factory unit during training or general plinking with the 5.7x28mm platform.

ProMag has long been a trusted name in aftermarket firearms accessories, and the FNHA10 carries that tradition forward. Whether you need a backup mag to round out your kit or a replacement for a factory unit that has seen heavy use, this blued-steel 5.7x28mm magazine delivers dependable performance at a value price point.
