I know you are referring to pistols, and correct on that. But can you have threaded barrel on a semi auto rifle in Md? As far as I can tell you can have one on a semi auto rifle in DC and don't need to obliterate or weld anything onto those threads..
and DC outright banned gun ownership as recently as 11 years ago. We should never ever forget, nor should e never forget to mention in discussions, that:
Even with background check
Even with registration
Even with training
Even with waiting period
Even with a gun safe
Ie even with every single "common single gun restriction"
DC would not allow law abiding citizens to even have a revolver at home. (and arguing with DC on that was EVERY national gun control group).
