Federal Child Safety Lock Act of 2005 effective April 24 2006 

 In October 2005, Congress passed and President Bush signed into law legislation making it unlawful for any licensed importer, manufacturer or dealer to sell or transfer any handgun unless the transferee is provided with a secure gun storage or safety device.
A “secure gun storage or safety device” is defined in 18 U.S.C. § 921(a)(34) as:
(A) a device that, when installed on a firearm, is designed to prevent the firearm from being operated without first deactivating the device;
(B) a device incorporated into the design of the firearm that is designed to prevent the operation of the firearm by anyone not having access to the device; or
C) a safe, gun safe, gun case, lock box, or other device that is designed to be or can be used to store a firearm and that is designed to be unlocked only by means of a key, a combination, or other similar means.
