California to be the target of gun smugglers.

When I first read through this I wonder how it would actually dry up firearm sales but as I re-read is see that is exactly what it is designed to do.

The new law, AB 1471, requires information about a gun's make, model and identification number to be laser engraved onto the gun's firing pin.
Theoretically, the information would transfer itself onto the bullet cartridge when the pistol is fired, allowing police to match bullet casings found at crime scenes with the gun that fired the bullet.

If manufactures are unwilling to make the changes in production, then new semiautomatic pistols would not be sold in CA. That brings up the question about firearms purchased in other state and then brought into CA. Back to the original idea though, this will only really affect those who will follow the law in the first place, since it is relatively easy to circumvent this law. One could change out compatible firing pins or just as easy file down the pin to remove the laser engraved image.

Criminals will be able to remove the laser engraving in moments, using common household tools, the group said. And it would be easy for criminals to scatter microstamped cartridges from other guns at crime scenes to confuse police, critics say.

Criminals do not follow the law, hence they are criminals, so there would be a gun smuggling industry into CA that will spring up over night. Of course this is only currently aimed at semiautomatic pistols, so shotguns (truly the best home defense weapon) are untouched.

One idea is that only criminals use these types of weapons or at least are the predominate users but what about law enforcement? If manufactures are unwilling to take the steps to actually make these laser engraved firing pins, what will police do?
