The USG variant pairs a polymer frame in Flat Dark Earth with a black slide shell over a steel core, creating a durable two-tone configuration. Markings include FN HERSTAL BELGIUM and FNH USA Fredericksburg, VA import information, confirming Belgian origin with U.S. import stamps.
Controls are purposefully laid out: frame-mounted ambidextrous manual safety levers are positioned ahead of the trigger, and the magazine release is reversible with a left-side setup. The external hammer is shrouded, and the trigger is single-action.
Sighting equipment consists of a white-dot front blade and an adjustable rear sight, supported by a 7.0 in sight radius for clear alignment. The pistol uses a 4.8 in barrel with a 1:9.1 in right-hand twist, optimized for the 5.7x28mm cartridge.
An integral multi-slot MIL-STD-1913/Picatinny rail on the dustcover provides mounting space for compatible accessories. Aggressive molded checkering and textured grip panels offer a secure, consistent hold.
The fired-case envelope is labeled "FsN IOM" while the pistol itself presents USG features, a known transitional mislabeling from the period before the USG gave way to the MK2 introduction in 2013. This documented detail offers added clarity on where this example sits in the model’s timeline.
