FN Five-seven

| Tuesday, May 31, 2011 | 0 comments

The FN Five-seven, is a semi-automatic pistol designed and manufactured by FN Herstal in Belgium. The pistol's name refers to its 5.7-mm (.224 in) bullet diameter, and the unusual capitalization style is intended to spell out the manufacturer's initials—FN.

The Five-seven pistol was developed in conjunction with the FN P90 personal defense weapon and the 5.7×28mm cartridge. The P90 was introduced in 1990, and the Five-seven was introduced in 1998 as a pistol using the same 5.7×28mm ammunition. As a companion pistol to the P90, the Five-seven shares many of the same features: it is a lightweight polymer-based weapon with a large magazine capacity, ambidextrous controls, low recoil, and the ability to penetrate body armor when using certain cartridge types.

The Five-seveN is a delayed blowback operated, semi-automatic firearm. It featured polymer frame with underbarrel acessory rail. The gun is available in two versions: Five-seveN standard, intended mostly for military users, and Five-seveN Tactical, intended mostly for Law Enforcement users who carry handguns as a primary weapons. The only difference between Standart and Tactical models is in the trigger type: the Five-seveN standard features Double Action Only trigger with long trigger pull and no external safeties; The Five-seveN Tactical featured Single Action trigger with short and light trigger pull and ambidextrous safety switch, located on the frame above the trigger. Both variants are striker fired, with internal firing pin safety. The sights are fixed, with optional night sights (with luminous dots inserts) available.

High magazine capacity: The Five-seveN® comes standard with 20-round magazine.

High stopping power: The Five-seveN® fires the 5.7x28mm SS190 Ball round which reliably penetrates Kevlar helmets and vests as well as CRISAT protection.

High hit probability: The Five-seveN's® extremely low recoil impulse results in virtually no muzzle climb, thereby facilitating fast and controllable follow-up shots.

Light and ergonomic: Weighing 30% less than most 9mm pistols, the smoothly-contoured Five-seveN® is comfortable to carry and quick to deploy.

Fully safe: Due to its double-action firing mechanism, the Five-seveN® offers no inherent risk of accidental discharge during transportation. Furthermore, all of its safety devices are automatically reengaged following each firing cycle.
