FN FNS-9C MAGAZINE SLEEVE FOR 17RD MAG

The FN FNS-9C Magazine Sleeve is a precision-fit accessory designed to extend your FNS Compact's capacity and ergonomics. If you carry an FNS-9C, you know the trade-off: compact size for concealment means a shorter grip that can feel cramped under recoil or in extended shooting sessions. This sleeve transforms a standard 17-round FNS magazine into a full-featured grip extension, turning your compact pistol into something that feels and handles like the full-size version—without actually carrying a full-size gun.

The genius is the simplicity: slip the sleeve over a standard-capacity FNS 9mm or .40 S&W magazine, and suddenly you've added rounds and extended the grip surface. For shooters who want capacity flexibility without swapping guns, this is a no-brainer. Grab a sleeved magazine for the range or home defense, or go bare for pocket carry. It's the kind of accessory that solves a real problem without adding bulk or complexity to your kit.

Built to FN's standards, the sleeve fits with precision—no rattle, no guesswork. Whether you're running drills at the range, training for defensive scenarios, or just want a more comfortable hold on your carry gun, this is an affordable way to tailor your FNS Compact to your grip and mission.
