-- "New Jersey Attorney General Matthew Platkin said, 'This amazing yet straightforward technology – imprinting unique identifiers on the firing pin of firearms – will have a profound impact on public safety across the state.'"
WAIT A MINUTE...
"Two things: 1) The technology only applies to semiautomatic firearms, as they are the guns that eject shell casings after each shot. Therefore, criminals who use revolvers will immediately circumvent the microstamping issue. 2). Maryland had a microstamping requirement for 15 years and ended it after spending $5 million to maintain the microstamping database but solving no crimes." --PS... You can buy a Colt 1911 firing pin for $19.99.
