FN FNS-40

Full-Size .40 S&W Pistol

The FN FNS-40 is a full-size, striker-fired pistol chambered in .40 S&W and built for duty carry, home defense and range work. A 4-inch barrel and 14-round standard magazine give it the sight radius and capacity of a service sidearm, and the ambidextrous controls let left- and right-handed shooters run it without changes. It suits anyone who wants a dependable .40 that is straightforward to operate and easy to set up for their hand.

Features

• .40 S&W Chambering — Fires the .40 Smith & Wesson cartridge, a common law enforcement and self-defense round that hits harder than 9mm in a similar-sized pistol.
• Striker-Fired Action — An internal spring-loaded striker fires the round instead of an external hammer, so every trigger pull feels the same from first shot to last.
• Cold Hammer-Forged Barrel — The 4-inch stainless steel barrel is shaped by hammering the steel around a mandrel, a process that produces a dense, durable bore.
• 14-Round Magazine — The standard magazine holds 14 rounds, with 10-round versions available where local law limits capacity.
• Ambidextrous Controls — The safety lever and magazine release work from either side of the frame, so the pistol handles the same in either hand.
• Interchangeable Backstraps — Two swappable rear grip panels let you change the size and shape of the grip to fit your hand.
• MIL-STD-1913 Accessory Rail — The rail under the barrel follows the military picatinny standard, so most weapon lights and lasers mount directly.
• 3-Dot Combat Sights — A front dot and two rear dots line up quickly for fast sight alignment.
• Front and Rear Slide Serrations — Grooves cut at both ends of the slide give you a firm grip for racking or press checks.
• Made In USA — The slide is marked as manufactured by FNH LLC in Columbia, South Carolina.

Build and Handling

The frame is checkered polymer, textured for grip and lighter than metal, paired with a black-finished stainless steel slide. It runs on a short-recoil action with a tilting barrel, the same locking system used by most modern service pistols. Overall length is 7.25 inches and weight is 27.5 ounces (780 g), with a trigger pull of 5.5 to 7.7 pounds.
