Carried this one for 13 years as a LEO. It looked as good as yours back in 1966.
The only ammo available back then was the hunting rounds and they were brutal with the factory PC magna grips.
I couldn't afford the $12.50 for target grips, so I destroyed the magna grips to get the hardware to make myself a set of "PC targets." The original grips would probably go for more than my gun today.

We survived some serious social encounters. The gun did what it was designed to do and got us home at the end of the shift several times.
