Submitted by National Shooting Sports Foundation on Jan 10, 2012 For the fourth year in a row, anti-gun legislators from New York City have introduced firearms microstamping legislation (Assembly Bill 1157b) that would result in banning firearms in the Empire State. Microstamping is a patented process that micro-laser engraves the firearm’s make, model and serial number on the tip of the gun’s firing pin so that, in theory, it imprints the information on discharged cartridge cases.
