The passage of Texas House Bill 957 (HB957), with an effective date of September 1, 2021, has generated questions from industry members as to how this state law may affect them while engaged in a firearms business activity. HB957 claims to exempt silencers (also known as suppressors) that are manufactured in Texas, and which remain in Texas, from Federal firearms laws and regulations, including the federal registration requirements. However, because HB957 directly conflicts with federal firearms laws and regulations, federal law supersedes HB957. In summary, all provisions of the Gun Control Act (GCA) and the National Firearms Act (NFA), including their corresponding regulations, continue to apply to FFLs and other persons in Texas.
