This Browning Hi Power represents the German-occupation WaA140 pattern, identified by the Waffenamt 140 acceptance stamps and the Pistole 640(b) designation. It was manufactured in 1943 at FN Herstal during WWII and carries the French-language FN slide legend characteristic of the period.
The pistol uses the internal-extractor slide configuration associated with early wartime production. It retains fixed sights with a front blade and rear notch, the ring hammer, a thumb safety, and a standard magazine release, all consistent with service features of the era.
Built on an all-steel frame and slide, this full-size Hi Power has a 4.7 in barrel and a 13+1 capacity. A lanyard ring at the heel supports its service-carry pedigree, and the included steel magazine is appropriate to the model.
Collector-oriented details include the WaA140 acceptance marks and the internal-extractor slide. The slide and frame share the same base number but have different suffixes and are non-matching.
