Or if you were really clever, get a second firing pin file it down use it for the crime and then replace the unaltered pin in your weapon. Not a bad idea to have a second barrel also.
And ejector.
And use frangible ammo.
Simpler to just by cheap 9 mils and toss them/destroy them.
Great minds think alike. :-)
The stupid politicians and movie actors talk about microstamping the "shell casings," which do not exist in ammunition parlance. If you asked them what a primer is, they'd scream: "racist"!
As far as I'm concerned, anyone who has never reloaded ammunition should refrain from making public comments on the topic of ammunition.
As an aside, I put this graphic together for educational purposes for those who think they're firearms experts.
