this is a complete joke. recycled brass may have multiple stamps and lead them on a while goosechase. any criminal with 10 cents worth of brains would use a stolen gun, probably with some parts swapped with another making the barrel and firing pin not match. any idiot in the world can take a fingernail file or even a plain old rock from their front yard and polish .001 off the pin removing the engraving. this is as stupid as asking them to microstamp little metal tags and put it in the projectiles. it's rendered worthless by technology dating back to the 1100's. (using fire to cast, or rocks to sand a surface) this is not only ineffective but will result in far more false hits than legitimate ones. stop legislating equipment, and try enforcing laws about behavior instead. better yet, take all this effort, and use it to investigate the corruption in our own government due to big business bribing congress to pass unfair trade laws that make america poor by shipping all the jobs to slave labor countries and most of this crime will go away on it's own. desperation and a large income gap between the elite and the hard working honest citizen carry a much higher correlation with violent crime than gun possession or use.

re-locate your manufacturing to sc!!

i own a gun and in several decades it has never once jumped up and shot me. this leads me to believe that guns may not be the problem. i also own several cats. they have on occasion jumped me while i was sleeping and left a scratch or two. this leads me to believe that the problems generally come from biological entities. i don't hear anyone suggesting we ban cats. it may be that we as a people need to admit that there is a problem (people) so that we can fix the problem (people) with something that will actually fix it. so, as always, police up your brass.
