The FN FNS-FNX .40 S&W 10-round magazine is a factory OEM magazine engineered to FN America's exacting specifications for reliable feeding and durability across extended duty and training cycles. Built from steel with a polymer base plate, this magazine delivers the precision fit operators depend on when magazine reliability directly impacts mission readiness.
The 10-round capacity meets federal and state compliance requirements while maintaining magazine stack-ability for efficient ammunition management in duty rigs and range bags. Steel construction resists deformation from repetitive loading cycles and impact, a critical factor during patrol reload drills or tactical training. The polymer base plate protects the magazine's feed lips from concrete impact and facilitates rapid strip-down for cleaning—essential maintenance for magazines that see regular service in humid environments or salt-air conditions. Dimensional consistency ensures flawless seating in FNS and FNX platform firearms without rattle or play.
This magazine suits law enforcement officers, armed security professionals, and serious sport shooters who rely on .40 S&W platform compatibility and OEM-level build quality. Whether for duty backup magazines, transition training, or field replacement inventory, FN factory magazines eliminate the variables of third-party production—critical when ammunition security and feeding are non-negotiable.
FN America magazines represent the OEM standard for the FNS and FNX platform. Operators choosing factory-correct magazines gain the same engineering tolerance and quality assurance that ships with new firearms, reducing downrange failure risk and simplifying parts standardization across duty teams.
