B&T designed this 9mm suppressor specifically for use with Glock firearms, but is compatible with any 9mm weapon that has M13.5 x 1LH threading. The B&T 9mm Glock suppressor is a popular choice among professionals who value its durability and practicality, as well as its ability to reduce a shot’s sound level to a whisper-quite 32 decibels. In addition, this suppressor is equipped with a unique spring booster, which facilitates reliable cycling of supersonic and subsonic cartridges.
