            |  | A BILL TO BE ENTITLED | 
         
            |  | AN ACT | 
         
            |  | relating to the definition of firearm for purposes of certain | 
         
            |  | criminal offenses. | 
         
            |  | BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS: | 
         
            |  | SECTION 1.  Section 46.01(3), Penal Code, is amended to read | 
         
            |  | as follows: | 
         
            |  | (3)  "Firearm" means any device designed, made, or | 
         
            |  | adapted to expel a projectile through a barrel by using the energy | 
         
            |  | generated by an explosion or burning substance or any device | 
         
            |  | readily convertible to that use.  The term [ Firearm] does not | 
         
            |  | include: | 
         
            |  | (A)  a firearm that may have, as an integral part, | 
         
            |  | a folding knife blade or other characteristics of weapons made | 
         
            |  | illegal by this chapter and that is: | 
         
            |  | (i) [ (A)]  an antique or curio firearm | 
         
            |  | manufactured before 1899; or | 
         
            |  | (ii) [ (B)]  a replica of an antique or curio | 
         
            |  | firearm manufactured before 1899, but only if the replica does not | 
         
            |  | use rim fire or center fire ammunition; or | 
         
            |  | (B)  a stun gun as defined by Section 38.14. | 
         
            |  | SECTION 2.  The change in law made by this Act applies only | 
         
            |  | to an offense committed on or after the effective date of this Act. | 
         
            |  | An offense committed before the effective date of this Act is | 
         
            |  | governed by the law in effect on the date the offense was committed, | 
         
            |  | and the former law is continued in effect for that purpose.  For | 
         
            |  | purposes of this section, an offense was committed before the | 
         
            |  | effective date of this Act if any element of the offense occurred | 
         
            |  | before that date. | 
         
            |  | SECTION 3.  This Act takes effect September 1, 2025. |
