by kcdsTM on FlickrSan Francisco PBS station KQED recently ran a report on the regulation that will require all guns sold in California to employ bullet microstamping technology. Each firearm will have a specially marked firing pin that will imprint a code on the bullet casing at the time of firing. While the NRA is up in arms with this, the only drawback presented in the report is that of incomplete stamping if the firing pin gets worn or damaged.

A question I have that the report didn't address: How easy is it to swap out the firing pin? Crime novel writers take note -- this could be an interesting plot resolution.
