I just picked up this FN High Power; its 5 digit all matching gun, perhaps early postwar (?), in pretty nice shape. Can anyone tell me what year this pistol was made and about the various proofs? I'm assuming that this is a commerical gun? Thanks.
The internal extractor was used on all Hi Powers from the beginning until it was changed in 1962. In 1962, the design was changed to the external extractor, which became the norm after all of the old parts were used up.
