Hey, Car Knocker, I'll argue. One of D. Saive's main jobs was to plow Browning design features back into a gun that Mr Browning had to design to evade his own patents assigned exclusively to Colt. When the patents ran out, FN used them. Key items being gun assembly tied to the slide stop, a thumb safety on the receiver, and a barrel bushing. (Yes, a BHP has a barrel bushing, even though it is permanently installed in production models instead of the removable 1911 type bushing shown in 1929.) Those are just the obvious ones I recall offhand, there are likely others.
