I suspect that if they have that microstamp, they could track the firearm anyway, without registration, thru the dealer network, assuming that it was not transferred illegally, or thru a private transaction.
I don’t have any problem with gun regulations that only impact criminals. The real challenge, though, is to actually put the thugs in jail once you’ve caught them. If you’re not going to do that, then what’s the point of the microstamp?
“I suspect that if they have that microstamp, they could track the firearm anyway, without registration, thru the dealer network, assuming that it was not transferred illegally, or thru a private transaction.”
You got it. If the microstamping of ammunition is to be effective, then the firearm must also be registered. Otherwise, there is no mechanism to link the ammunition to the gun.
If they're criminals, then they've already broken laws. Is an armed robber going to care about a gun regulation? Is a murderer?
Gun regulations are intended to ensnare the otherwise law-abiding citizen.
