What happens when you change out the firing pin? It doesn't cost much at all, depending on the weapon, and takes about 5 minutes.
They'll probably require that the new firing pin be put into a gun and used to produce a few cases for the state. This will make it slower and more expensive to sell the things and thus more expensive to buy. The fewer people who can afford firearms, the better as an armed population might be more dangerous to the state.
this will increase the regulation about firing pins making the PINS so expesive as to make your gun useless.
This is about regulation based outlawing.
This is an effort to de-facto repeal the second amendment.
An EXTREME taking in the constitutional sense of the word.
