1978 Browning Hi-Power 9mm near golden gate park, San Francisco, CA

One of my Grandfather's pistols that he left me when he passed. Not too sure its history but it's a 1978 model, made in belgium, chambered in 9mm, with a Monrovia, CA, 1975 embroidered holster and one magazine. Seems in quite good condition. Probably didn't see much action because he was a lawyer; it was probably an antique or gift of some kind. Haven't shot it but it cycles and chambers normally.
