Question of the Day: Was Nickel Plating a 70’s Thing?

My father was a Denver cop from 1963 until retiring in 1988. Amongst his numerous weapons, a Browning Hi-Power was his favorite non-service gun. At some point, he decided that nickel plating would be a nice touch. He passed away long ago, so I missed the chance to ask him why opted for plating the pistol. A good idea back then Today?  I’d love to hear some feedback from TTAG’s Armed Intelligentsia. BTW, it’s my favorite gun to shoot, and it works flawlessly. [The best thread I found while researching this blog:]
