A licensed firearm dealer may not sell, lease, or otherwise transfer a firearm without an accompanying child safety lock suitable for that firearm. The dealer must provide the child safety lock to the recipient of the firearm when transferring the firearm. The dealer may charge for the child safety lock. A licensed firearm dealer who sells, leases, or otherwise transfers a firearm must post conspicuously in the dealer’s place of business:a notice of the prohibition in <cite data-path="|19|§59-12">§ 59-12 of this Part</cite> against leaving a firearm where an unsupervised minor can obtain access to it; and a notice of the prohibition in subsection (a) of this section against the transfer of a firearm without an accompanying child safety lock. If the transaction occurs outside the dealer’s place of business, or if the dealer does not maintain a place of business in a commercial establishment, the dealer must provide the required notices in writing when transferring the firearm.
