I would shoot it. A 1979 is not even a C series pistol. It is a MKII and they made a ton of them. Even T series collector value is overblown IMHO. They bring a premium but not as much as some people think.

If the gun has been shot at all its true collector value has been diminished unless it is a WWII gun then the historical significance starts to come into play.

Enjoy the new BHP!
