The Grey Ghost GGP-17 threaded barrel (brand part no. BARREL-G17-T-NC) is a drop-in 9mm match barrel for the Glock 17 in bare non-coated stainless, threaded 1/2×28 and shipped with a thread protector. Grey Ghost Precision machines it from 416R stainless steel with a 1:10 twist and a SAAMI-spec 9mm match chamber, holding final dimensions to three thousandths of an inch for consistent accuracy. The threaded version measures 5 inches overall against 4.5 inches for the non-threaded barrel, and it weighs 5 ounces, so a compensator or suppressor mounts without changing how the pistol carries. Grey Ghost makes the GGP-17 for both Gen 3-4 and Gen 5 Glock 17 slides and specifies brass-cased factory ammunition. For a Glock 17 headed toward a suppressor or a compensator, this is the match barrel that keeps the stainless look.
