re: Taking our Guns.....how do they do it?

They will try and crack down on manufacturers and ammo suppliers, gun stores (online and B&M) before they start going after individual owners. Making it hard/impossible to buy new guns eliminates future generations or gun owners therefor less people will grow up with them. The door to door removal will never happen. Too many LEOs will decline due to risk and most will just report stollen or lost.

You will see conservative States becoming “sanctuary states” for gun ownership and not enforcing buy backs etc.
