I have a question that those of you familiar with Browning HIGH Powers may be able to answer for me. I have a chance to buy a HP with serial number beginning with 76C. I believe that this indicates the production year was 1976. I also believe that this would mean that the gun was manufactured and assembled in Belgium. The question is, are these assumptions correct concerning this gun? The next question is how rare/uncommon would a nickle plated BHP with target sights be? Thanks in advance for your help.
