FNH FNS-40 – .40 S&W Semi-Automatic Pistol

The FNH FNS-40 is a full-sized, striker-fired semi-automatic pistol engineered by FN Herstal (Fabrique Nationale) to deliver reliable performance, rugged durability, and precise accuracy. Designed for law enforcement, personal defense, and professional use, the FNS-40 combines modern ergonomics with FN’s reputation for exceptional firearm craftsmanship.

Key Features:

Caliber: .40 S&W

Action: Striker-fired, double-action operation

Capacity: Typically 14+1 or 10+1 rounds (magazine dependent)

Frame: High-strength polymer frame with replaceable backstraps for customizable grip fit

Design and Ergonomics:

The FNS-40 offers a low-bore axis for reduced muzzle rise and faster follow-up shots. The fully ambidextrous controls—including the slide stop lever and magazine release—make it equally convenient for both left- and right-handed shooters. Aggressive front and rear slide serrations ensure secure manipulation even in adverse conditions.

The pistol’s textured grip surface and interchangeable backstraps provide a secure, comfortable hold tailored to different hand sizes. The polymer frame helps absorb recoil while maintaining durability and reducing weight.

Trigger safety

Firing pin safety

Drop safety
Some models feature a manual thumb safety as well.
The FNS-40 is designed for consistent trigger pull, fast reset, and reliable ignition under all conditions.

Sights and Accessories:

Three-dot fixed sights (or optional night sights on certain variants)

MIL-STD 1913 Picatinny rail for easy attachment of lights or lasers

Performance:

Renowned for its smooth trigger, robust build, and combat-grade reliability, the FNS-40 performs exceptionally well in both defensive and duty roles. Its balance and recoil control make it a solid choice for shooters who prefer the .40 S&W cartridge’s power and penetration.
