They want ‘locking devices’ supplied with all firearm sold, not just handguns.
It's a big win for the lock manufacturers. I never use the locks bundled with my firearm purchases. My wife DID use a bundled lock on a shotgun purchased in San Diego. We moved to Idaho. The shotgun was in the safe. The key was lost. Solution? I purchased a set of lock picking tools from Amazon. It took less than 10 seconds to pick. The removed lock was immediate re-locked to itself.
