Nothing significant, I'm sure. It's been joked before that it's a gay pride gun, and my father was living in San Francisco when he bought it in '48, but I believe it's just the colors that were available at the time and I'm sure my father just thought they looked good. He also made a small jewelry box for his girlfriend at the time. She became his wife, my mother, and 11 other siblings followed.
I think he just got carried away with the idea of "sweetheart grips". He made a set of sweetheart grips earlier while in France during WWII. They were for a WWI Spanish Izarra he picked up over there.
FYI, he kept and I have the original grips for both guns.
