New York enacts microstamping gun law in push to change how firearms are made

New York this week became the second state to pass a law attempting to force gunmakers to adopt microstamping, a technology that imprints tiny codes on casings.

California passed a similar law 15 years ago. Since then, no handgun capable of microstamping has been introduced for sale in that state.

Instead, gunmakers have pulled new handgun models from the California market rather than equip them with the technology, which critics say is costly, unworkable and of questionable value as a crimefighting tool.
