    I have a used griffin match glock 19 barrel. It’s very accurate and the comp surprisingly helps mitigate recoil pretty well. Comes with original packaging and ready for use. Shows some slide wear and also a couple spots from removing the comp. roughly 400 rds through it.

    For sale is a lightly used (200-ish rounds) Zev Tech V2 Pro comp for a Gen 5 Glock in 9mm. Some minor wear throughout and carbon in/near ports. Selling because I decided to go with a lower profile comp. When used with a Glock 19 it becomes the length of a Glock 34.
