Bunny-hugging libs always trot out the musket comparison. They forget that in 1776, ANY torso wound resulted in agonizing death over hours or days. Any limb wound resulted in an amputation at best, and still often an agonizing death.
Not to mention that "assault weapon" of the time, the blunderbuss, which could fire 30 or more rusty nails or lead pellets with one pull of the trigger. Each one of those wounded would risk an agonizing death from infection.
Any thinking person must factor in modern medical care along with modern weapons. I'd rather be wounded with a modern weapon, with modern medical care available, than take a dirty lead ball in the guts in 1776.
If you resurrected any one of the Founding Fathers and told him that the Feddle Gummint had passed legislation restricting the right of common citizens to possess the military issue shoulder arm of their country - NO MATTER WHAT it was at the time - you'd find him starting a revolution to overthrow the Gummint the very next day.
