Today is Pistol Patent Day. it is based on the day that Samuel Colt got his U.S. patent on his revolver in the United States in 1836. He had already obtained the patent in Europe in 1835. The patent # is 138.
All that said, as I understand it, a pistol today is considered an automatic, or semi-automatic weapon. Like the famed Colt 45, so a pistol is technically not what Colt invented. he invented a revolver that does not fire automatically by pulling the trigger, rather is has a chamber that revolves around the firing pin.
I don’t know that really matters. I think maybe it should be called hand gun day instead of pistol day because an old flintlock was neither automatic nor a revolver and yet it was called a pistol. But, today is the day we celebrate them… whatever they technically are.
How to celebrate – If you own a hand gun, go target practice. Make sure you have a lock on your pistol to keep it safe. Read about the history of the pistol.
