I've studied Patton and he took extreme offense when someone

referred to his pistols as being "Pearl handled" when they were indeed Ivory handled. happy

"Only a pimp in a New Orleans whorehouse or a tin-horn gambler would carry a pearl-handled pistol."

Technically he was not in violation of any military codes by wearing those pistols.(Colt 45 on right hip,S&W 357magnum on left hip).Most other officers and all enlisted men would have been in violation but not Patton.

Being a General when he entered the action of WWII, Patton had the prerogative of "designing" his own uniform. This privilege allowed him to wear those pistols and any other accoutrements as he desired.
