This Model 1910 uses a simple blowback, striker-fired, single-action-only system. Its safety suite includes a manual safety, a grip safety, and a magazine disconnect. The European heel-type magazine catch is located at the base of the grip.
The pistol retains classic 1910 pattern features: rear slide serrations only, a fine anti-glare rib running the length of the slide top, and a knurled/takedown muzzle bushing at the slide nose. Sights are fixed, with a small front blade and an integral rear notch for a low-profile sight picture.
Markings and proofs are well represented. The left side of the slide reads: "FABRIQUE NATIONALE D'ARMES de GUERRE HERSTAL BELGIQUE" over "BROWNING'S PATENT - DEPOSE." The barrel hood is marked "CAL 9m/m." Belgian proof marks appear on the barrel hood, the left frame shows the FN oval cartouche, and additional non-Latin inspection/property marks are present below the slide address. The serial number is located on the frame above the trigger.
The micro-size steel frame and slide are finished in blued steel, paired with smooth wood grip panels held by a single screw per side. Capacity is 6+1 in .380 ACP, and the included magazine is a steel single-stack design with five witness holes and a flat floorplate.
