Relating to the prosecution of the offense of unlawful transfer of certain weapons.

HB 4372 amends Texas law to increase penalties for unlawfully transferring firearms, directly affecting gun sellers, dealers, and individuals purchasing firearms. It prohibits selling firearms to minors (under 18 for most weapons, under 21 for certain firearms), people under the influence, those with recent felony convictions, or individuals subject to active protective orders. The bill also bans false statements on firearm transfer forms and adds specific restrictions on firearms capable of accepting detachable magazines using centerfire ammunition or larger than .22 caliber. A limited defense is included for short-term firearm rentals at shooting ranges for training or competition, with parental permission required for minors.
