Our external booster assembly is made of 316L stainless steel for a lifetime of problem free use. Ships with a heavy spring installed and a spare medium spring in the bag.
The booster piston is threaded 13.5x1mm on the barrel end to fit most Metric European 9MM barrels.
The booster is threaded 1/2-28 on the silencer end to fit most silencers threaded for 9MM and 380ACP applications. Turn your rifle silencer into a pistol silencer. Quick and easy screw on installation.

A booster is required for all handguns that utilize the Browning-type action (Glock, Sig, HK, S&W etc.) The use of the booster allows the pistol to properly cycle when the weight of the suppressor is added to the end of the barrel.
