Two possible scenarios for microstamping

Gun control advocates believe newly passed legislation will force manufacturers to adopt microstamping.

From the Associated Press:

“New York this week became the second state to enact a law intended to force firearms manufacturers to adopt microstamping, a technology in which guns imprint tiny codes on ammunition cartridges as they are fired — creating a unique signature police could use to help solve crimes. Big questions remain, though, about whether the new law will actually result in such guns being offered for sale … “The New York legislature has set up a more robust system that will produce a set of conditions and evaluations that doesn’t rely on the gun industry to give them a thumbs up or thumbs down,” said David Pucino, of the Giffords Law Center to Prevent Gun Violence …”

The technology does not work.  It cannot work.  Both the firing pin and cartridge are moving in the chamber and hit each other multiple times at slightly different offsets resulting in a smeared mark.

One of two things is going to happen: Either the state will simply declare microstamping to be “viable” anyway resulting in stopping all new pistol sales, or it will never go into effect and be another failed boondoggle like CoBIS and the ammunition sales check database.
