A new form 4473 was introduced this month. The ATF sent out an alert to SOME FFL dealers telling them to start using the new form. In this case the FFL must download the PDF from the ATF and print it at their own expense. The ATF does not have the new 4473 forms in the supply chain yet.
The e4473 has not yet been updated but the ATF claims it will be updated before FFLs are required to use the new 4473.
The new forms will be required in early 2023 (I remember February but my rememberer is not all that good.)
The first three pages of the new 4473 are included hear with markup showing the changes. There might be more changes in the seller section but I did not check those sections.
