provide that a firearm silencer is not a controlled weapon.

SB 2 amends South Dakota law to clarify that firearm silencers (devices reducing gunshot noise) are not classified as "controlled weapons." This change removes silencers from the category of weapons subject to strict state regulations, such as special permits or licensing requirements. The bill directly affects gun owners, manufacturers, and sellers of silencers in South Dakota by eliminating these regulatory barriers. The key mechanism is an amendment to the definitions section of the state's criminal code (§ 22-1-2), specifically excluding silencers from the definition of "controlled weapon."
