“This is where microstamping comes in. If it were required, every gun would need to have a microscopic code stamped on the tip of its firing pin. When a bullet leaves the gun, its shell casing would be stamped with the code, which could be retrieved from the casings found at crime scenes”.

There are millions of guns in circulation without any such micro stamping, a new firing pin would leave no marks, someone could easily police their brass or use a revolver thus leaving nothing to examine....for these reasons it's not workable to try unique micro stamping.

There is an amazing technology called a “file” that would take care of microstamping in a heartbeat.

Microstamping is a transparent effort at universal registration, and to make guns less affordable.

If something like this were desirable, it’d be easier to pre-engrave the brass and register ammo sales. Of course, criminals would just deface the engraving, so it’d be useless as well - except for controlling those pesky law-abiding citizens a bit more.

They would probably pass a law outlawing shell catcher bags and revolvers.

When shell catcher bags are outlawed only outlaws will have shell catcher bags.

How does this work on revolvers? I mean unless the perp stops and empties his gun how will microstamping help when a perp uses a revolver?
