I think this is done in Kalifornia...and I thought there was an extra ‘charge’ to have this test fire done.
My assumption was that there is indeed a database of test fires for all weapons legally sold in Kalifornia.
I don’t believe ANY state has passed this useless balistic test. Pins and barrels can and are changed.
This is more a quality control issue I believe.
Before we start assuming or this turns into a “conditioning” (see frog in boiling water) to get the sheep used to the balistic dna test we have to talk to someone who actually knows.
(kind of like that BS UK tv detector to force people to pay their tv ownership tax)
