Maybe I'm reading things wrong. Maybe I've been doing things wrong, but...
I thought that FFLs were already supposed to be providing lockable options for their customers.
I got gigged on a compliance inspection several years back because I didn't have readily available trigger locks for firearms during transfers.
Have always kept them on hand ever since.
As to the times where police departments and sheriff departments give out gun locks.
Interestingly, they usually (in my experience) have a very low limit on the number of locks that you can get at a time.
I wanted 10 once and got weird looks and told I could have two and that was "stretching it."

Years ago I was at the Tulsa Co Fair and Project Child Safe was handing out locks. They seemed more than happy to let me have as many as I wanted.
