That's really interesting. An HP double-action model.
None of my reference books, including the Fjestad Blue Book show a 3.9" barreled FN-made or Browning marked double-action semi-auto. The ones listed are 4" barrels, or longer.
It looks authentic, and relatively new (case, etc.) Wonder what the story might be?
The values attached to the double action/single action models are considerably less than the single-action versions in the Blue Book.
