As we see it, the technology to implement the micro-stamping is flawed, there would be an increase in the potential for civil liability for law enforcement agencies that continue to use handguns which will be placed on the "unsafe" handgun list, there would be an increase in law enforcement training costs due to not being able to reuse spent cartridge casings, the technology could be easily defeated since the stamping is only 25 microns deep and the cost of the technology would be passed on to law enforcement agencies and citizens alike.
