This is an Agency Arms Mid Line match-grade drop-in barrel for the Glock 17 in 9mm. It’s fluted, threaded 1/2x28 for comps and suppressors, and finished in a durable black coating for hard use. If you want a cleaner lockup, better support, and a barrel that actually belongs in a serious build, this is it.
Heads up: Agency makes different Glock 17 barrels by generation. Buy the wrong gen and you just bought a very expensive paperweight.

Tools needed

Install notes
- Field strip the pistol and swap the barrel like a normal Glock barrel change
- Do a function check before live fire: smooth lockup, slide cycles freely, and it returns to battery consistently
- If running a suppressor or comp: confirm shoulder engagement and alignment, then test slowly before you go full send
- Use the thread protector when not running a muzzle device to protect the threads
Any required warnings/notes
- Return prevention: This is for Glock 17 Gen 1–4. If your customer has a Gen 5, they need the Gen 5-specific Agency barrel, not this one
- Threaded barrels may require suppressor-height sights depending on your setup
- Verify local laws and range rules regarding threaded barrels and suppressor use
- Data cleanup: your product line is missing a UPC and shows retail price as 0 — fix before import
