I know how that works, I know what a frame is, and I don’t care what the ATF website says. All I’m saying is that you can’t trace a gun that has no serial number to figure out where it came from in the event of a crime if it has no serial number.
ATF: “Yes, poly80, can you please tell me who you sold a black piece of plastic to?”
Poly80: “yeah, do you have a sn?”
ATF: “it doesn’t appear to have one.”
POLY80: “HAHAHAHAHAHAHAHA! Here’s 500000 names, pick one.”
Compared to s&w
ATF: " YES, I have this serial number, can you tell me where you shipped it to?"
S&w: " sure can! It at the academy in Galveston. Here’s the address…"
ATF: calls academy “can you tell me who bought sn: 929364738393736463627282635463?”
Freaking academy: " billy bob jangles bought it 7/15/2010"
ATF: goes to talk to Mr. Jangles.
