When I was 10 years old, my father, as a shooter of local renown, was invited to a demonstration for the local police of the then new Stoner rifle, (Now, the original M-16). I was allowed to go along. The salesman showed that the recoil was so light that he could shoot it with the butt on his chin. They had a cinder block wall set up and to show how powerful it was, and yet had light recoil, the salesman let me run 5 rounds full auto through it.
The dust flew. The Police Chief was not impressed, because blowing a perp to shreds at high noon on Main Street was not good PR. Police, in those days, were all WW2 vets.
And ‘in those days’ they had revolvers on their hips and a 12 gage loaded in the car.
I just want something that will disable - or even just seriously intimidate - any ‘home invader’ without killing him. (I don’t want to kill anybody, if there’s a better way out.)
What is it that they say? “When seconds count, the police are still minutes away.”
But I’ll have to move to a much different state, before I can have an AR-15 :-)
