Microstamping is like the failed COBIS case collection.
In theory its a case cracker. In reality, it doesn't work, will cost millions per year with nothing to show for it, and will quickly be abandoned after its shown what an embarrassing failure it is.
COBIS wasted millions and was never once used to solve a criminal case...
They never even found the money to create the ammunition background check system, where will they find the millions to create a database for a technology that doesnt exist yet....
They might even pass this stupid law, but they wont be able to enact it. It would take about three seconds to have a federal judge give it the smack down on the simple basis of there is no manufacturer that makes a compliant pistol, PLUS the technology to make it work doesnt exist. The injunction would arrive faster then the law did. Same crap as the 7 round mag limit that was smacked down in the safe act.
