The SilencerCo 9mm threaded barrel for Glock 17 (SilencerCo part no. AC864) is the replacement barrel that lets a Glock 17 take a pistol suppressor. It is 5 inches long, threaded 1/2×28, and made of 416R stainless steel finished in black nitride. SilencerCo notes that all pistol suppressors need a threaded barrel and built this line to the same standard as its suppressors. A thread protector ships with the barrel to keep the threads covered when no suppressor is attached. It is a direct replacement for shooters building a suppressed Glock 17.
