I can make a shotgun using a pair of black pipes, in less than an hour. Only need to drill one hole. Just not that hard, but outlaw them and people that would never consider making a firearm will set up production lines.

I have a nice 3-D printer, and only a fool would use it to print a gun. A simple block and a hand held drill motor will make a reasonable accurate hand held pistol. 3-D printed guns are just intended to piss off liberals, and could only be possibly viable; if the printed part was used to cast a metal part.

All you get by delaying a person with Murder in his heart is a murder with a bat or a knife. The heart is the real problem here, and a madman will not wait. BUT if the Victim is carrying a defensive firearm, the bat or knife will NOT be very effective!

The government does NOT have the Constitutional Authority to restrict Firearm ownership by Citizens.

You want to know the risk our Founding Fathers worried about? Look up Democide, THAT is what they worried about when they wrote the Second Amendment. They wanted us to be armed Equally with any standing Army the Government has, to avoid Democide problems.

Stay safe!
