FN Five-seveN USG 5.7×28 mm Semi-Auto Pistol, 4.8″ Barrel, 20-Round Capacity
This early-generation Five-seveN USG offers the original configuration that preceded the later Mk2 and Mk3 updates, making it a desirable link in the model’s evolution. Chambered in 5.7×28 mm, it pairs rifle-like velocity with remarkably light recoil in a full-size handgun weighing about 21 ounces unloaded. The pistol’s chrome-lined, cold-hammer-forged 4.8″ barrel resists fouling and wear, while the polymer-sheathed slide keeps reciprocating mass low for reliable function. Collectors and shooters alike value its 20-round flush-fit magazines and ambidextrous, index-finger-operated safeties.

The USG variant features a reversible square magazine release and ambidextrous frame-mounted safeties with a clear red dot fire indicator, accommodating both left- and right-handed users without modification.
A straight, serrated-face trigger houses an internal hammer and works within a delayed-blowback system, delivering a consistent single-action pull while managing the bottleneck cartridge’s pressure safely.
The slide’s polymer over steel-core construction reduces overall weight and lowers reciprocating mass, aiding reliability and minimizing muzzle rise during rapid fire.
Fully adjustable three-dot iron sights enable precise windage and elevation corrections using the included adjustment tool, enhancing the pistol’s practical accuracy at distance.
Proof marks reading “FN HERSTAL BELGIUM” and “FNH USA, FREDERICKSBURG VA” confirm Belgian manufacture with U.S. assembly and import, aligning with the production period of the late 1990s through 2012.
