From TPWD news release:
"Regarding the proposed amendment allowing the use of silencers, the department has determined that there is no resource- or enforcement-related reason to prohibit the use of firearm silencers for the take of alligators, game animals or game birds, and therefore proposes to eliminate the current prohibition. The department notes that if the proposal is adopted, it will not relieve any person of the obligation to otherwise comply with any applicable state, federal, or local law governing the possession or use of firearm silencers."
