It’s all grandfathered. I can keep and use all of my guns and magazines for as long as I live. By coincidence every gun and mag I ever own will have been magically bought pre-ban.
The day before chickenlooper signs it, I'm giving all my firearms and magazines to my son. He is of course entrusting me with their safekeeping and routine maintenance, check firing, etc...
Maybe. Have to see what it says about possession of someone else's firearms. Of course the local Sheriff has said that as far as he's concerned he is going to assume every firearm and magazine he comes across was purchased pre-ban. Every one, from now on.
