Yeah, by the time you get it out of the safe, assemble it and find the ammunition it’s too late.
Don’t need to assemble it, but do need to have it locked up and ammunition locked up separately.
I can be armed in less than 30 seconds from waking up. Is that too long? Yes, I think so. But it’s still a long way from a ban.
I have stopped burglars in my home twice quite successfully. Only once with a weapon - the first time I actually forgot I had weapons, I was so shocked and stunned.
