Hand guns in the USA are not going away soon.
We grew up with them on TV and in games. Gun training was a right of passage in school. In scouts it was a coveted merit badge. But, you know what? I've never shot one. I have my dad's old ACP that probably needs to have the barrel re-reamed but I figured the accuracy would be too bad to make it worth using. About the only way you could reduce hand gun usage now would be to change the caliber of the bullets. Make them .002 inches bigger in diameter so they jamb in the barrel.
