If your point is ,that there were a lot of hand guns around during the birth of our country, you would be mistaken. Note a 1800 pistol is decades after the 2nd amendment.
Washington was impressed by the citizen who augmented his army. They were helpful and he appreciated them. That is why the militia is referred to in the 2nd. amendment. They were armed with private weapons and shot at the Britts from cover. They did not confront them with dueling pistols. Pistols were not significant weapons in the revolution. The militia reference is clear. The Brits confiscated the muskets of the Americans when they could. The genesis and point of the 2nd is obvious unless you want to twist it into a handgun bill. It is not.
