Glock 19 Gen 1–5 – Threadless Comp + Barrel Kit – Ball-Vise – 4.5"
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
Made by Zaffiri Precision, this Threadless Comp + Barrel kit gives your Glock 19 compensated performance without using traditional barrel threads. The system uses Zaffiri’s Ball-Vise locking method (steel ball bearing + single set screw) to clamp the compensator to the included barrel—so you get a flatter, faster-returning gun with a clean install that doesn’t involve timing washers or thread drama.
Available options are organized below under Variants.
