This isn’t related to storage of guns in gun stores. It means gun dealers will have to offer gun safety devices or gun safes for sale. If simple trigger locks meet the requirements, then no problem. If it means gun dealers have to stock large gun safes for long arms, then it’s going to be a problem for shops (and pawn shops) without much floor space.
Gunsmiths hold FFL licenses. If the BATF tries to include all FFL holders in the regulations then it will put a lot of gunsmiths out of business.
This is meant as harrassment and you can bet the BATF is going to try to force the most expensive and inconvenient interpretation on FFL holders.
“If simple trigger locks meet the requirements, then no problem.”
They do. See Post No. 15.
