South Dakota took suppressors off its controlled weapon list in 2026
SDCL 22-1-2(8); SL 2026, ch 96
“‘Controlled weapon’ includes a machine gun and short shotgun, but does not include a firearm silencer”
Senate Bill 2 of 2026, effective July 1, 2026, rewrote the controlled weapon definition to exclude firearm silencers, so the Class 6 felony in § 22-14-6 no longer covers them. Before that change a silencer was a controlled weapon, and owners relied on the exemption for weapons registered with the proper federal authority.
