Thus the repeated saying by my grandmother, "If you take all the guns away from the law abiding people, only the criminals will have them." I also remember one of my underclassmen secretly (and illegally) making one in machine shop.Criminals will always be able to get hold of a gun if they really want one.
Nevertheless, we (U.S. members) are in a debate with modern members of the very country that gave cause to the constitutional mandate in the first place. Most handguns, as well as the rifles/muskets were single shot items at the time and there was no distinction of necessity. The other aspect, very dire in our early history, was a very wild environment and just firing any gun into the air was enough to scare many wildlife threats away; this still persists in some places and survival is limited without a firearm.
I was five-years-old at the time I first shot a .22 calibre rifle (my uncle's, with him there) and have also used a 9mm as well as the M-16. The only creature I ever killed (again with a .22 rifle -- my own -- but when in my teens) was a porcupine ruining our golden delicious apples when throwing sticks at him didn't chase him off (never collected the bounty, little as it was, anyway). The only handgun I used was a .22 revolver and only as a target weapon.
