Suddenly I want to nominate Beave for 'Hilarious' medal.  

Beave, let's say there was a registry to track every gun, 24/7/365.  
There are plans out there on the interwebz, and you can go to Princess Auto and buy a couple machines that will let you make your own untraceable guns!
https://globalnews.ca/news/3690529/seiz ... nist-shop/Registries only matter to honest people, the people you generally don't care about.  What we need is the ability to restrict the people who buy 50 handguns if they aren't a gun dealer.  Those are the ones selling to criminals.
All kinds of people sell guns to criminals there’s not one kind.  Some are honest, some are not some are just willfully blind or naive about who they’re selling to. In the US you can find people selling old guns they don’t want anymore in the Pennysaver and in flyers taped to telephone poles.  
I mean come on. Most gamgbaners and street thugs and deranged spree shooters are not manufacturing their own weapons. Have their been any significant number of crimes with these homemade guns?  I’ll bet they’re pretty rare. 
Registries help keep legaly sold guns legal because the gun can be traced back to the purchaser. You wouldn’t rob a bank using your own car and you wouldn’t let a friend use your car to rob a bank for the same reason. Nor would you agree  to rent a car under your name for your criminal friends’ crime spree.   Why?  Because you know it would trave back to you. 
Let me tell you and Martin and Pluggy about Straw Purchases. That’s when someone with a clean record legally buys a gun at a gustore, secretly on behalf of someone else whom they are working for or traffic guns to.  Gangs and organized crime groups employ a number of affilites this way but people also do it freelance. Straw purchasing is a major source of crime guns. If every gun sold had to be registered at the point of sale there would be no straw purchasers because those buyers would know every crime gun could be traced back to them. Also the sheer number of guns being registered to a single person would/should trigger a law enforcement intervention. 
Now there are two other ways criminals and smugglers  get guns:  one is through unscrupulous gun dealers who sell weapons illegally and the other is theft. Those are the only ways, even in the US.:  either the gun dealer is crooked, the gun owner is crooked, or the gun dealer or owner owner gets robbed. If we could  better trace these weapons from their legal source to the entrance to the criminal market we could crackdown on gun trafficking. 
And that’s an important point you guys over look:  just about  every (non-homemade) gun in this world was manufactured legally and intended for a legitimate and legal purpose and somewhere along the way a huge number  of these legal and legitimate guns cross over from the law-abiding world to the criminal world.  Gun advocates’ complete lack of curiosity about the ways that happen and how to curb it is simply ideological head-in-the-sand, Oppositional Defiance Disorder. I mean we investigate how stolen cars, contraband, and all other things enter the black market but for some reason this little hobby of playing with bang-sticks is sacrosanct and we must not ask any questions?  If you have to register your car, your boat, your airplane, should have to register your gun as well and you shouldn’t be able to buy one without that happening at the point of sale before you take possession.
