Recently, I became aware of a California law passed in 2007 that requires all semi-automatic pistols to have the breach face and firing pin be marked with the make, model, and serial number of the weapon that fired the spent round. This law is supposed to allow easier tracking of spent cartridges found at a crime scene back to a specific firearm without needing to recover the firearm used.
As the title indicates, I am a little skeptical about this particular method to trace firearms used in crimes. My question for this forum is simple. is this effort worth the expense? Is this even feasible at this time? Basically, will this be good or a waste of money? Please explain your answer.
