“.except that I saw the video showing a dude using a rubberband on the trigger which gave the same result.”
So when the antis see your post, will they try for a rubber band ban or a semiauto ban?
Definitely a ban on semi-autos. They've already started with the ban on so-called high capacity magazines (30 is standard capacity for an AR-15, so...). Even 5 rounds in a shotgun is too much for some folks.
They've already stated their disdain for semi-autos so we'll be hearing about that. Even a double-barrel shotgun is probably one barrel too many for these folks. If you can fire again in under 5 seconds, well, they don't like it.
Wouldn't surprise me to see the invention of something for bolt action rifles that deliberately slows down the cycle rate. Think about the QWERTY keyboard and how it's layout was actually designed to slow down typists to prevent keys from jamming. Yeah, it'll be that level of stupidity.
Before long someone will suggest that since only muskets and muzzle-loaders were around in 1789, that's surely the only thing our founding fathers had in mind and the only types of firearms we should be allowed to have. (excepting of course the paid security for our dear leaders and movie stars, who will get taxpayer funded full autos).
