Mauser coded this pistol byf 43 for 1943 production at Oberndorf, aligning it squarely with mid-war manufacture. The slide bears the correct eagle/135 – eagle proof – eagle/135 acceptance sequence, a hallmark of Mauser-inspected P.38s from this period.
Markings and serialization are notable. Matching numbers are observed on major components, and the barrel/locking block carries the letter suffix n. A small part shows the eagle/359 inspector mark. The safety lever retains red F paint, and a lanyard loop is fitted at the heel.
Mechanical and configuration features are correct for the model: a DA/SA short-recoil system with a falling locking block; an open-top slide with coarse cocking serrations; a slide-mounted safety/decocker; and a loaded-chamber indicator on the slide spine. Sighting is via a fixed front blade on the barrel band and an integral fixed rear notch.
The pistol uses black ribbed phenolic (Bakelite-type) grips and a heel-type magazine catch, with an 8+1 capacity in 9mm Luger. It retains the standard 4.9 in barrel and full-size steel construction associated with WWII-era P.38 service pistols from Germany.
