Frequently Asked Questions
Will this barrel fit my Glock 17 Gen 5?
The Agency Arms Mid Line barrel is designed for Glock 17 Gen 1 through Gen 4 pistols. Gen 5 Glock 17s feature a different barrel and frame geometry, so compatibility is not guaranteed. If you own a Gen 5, we recommend contacting Agency Arms or our store directly to confirm fitment before purchasing.
What suppressors or muzzle devices are compatible with the 1/2x28 threading?
The 1/2x28 thread pitch is the most common standard for 9mm suppressors and compensators in the U.S. Most major manufacturers — including SilencerCo, Dead Air, and Griffin Armament — produce 9mm suppressors compatible with this thread pitch. Always verify with your specific suppressor manufacturer to confirm compatibility and check your local regulations regarding suppressor ownership.
What is the advantage of the Mid Line over the Agency Arms Standard Line barrel?
Both the Standard and Mid Line barrels share the same core accuracy and reliability thanks to Agency Arms' pull-broached SAAMI-spec rifling. The Mid Line steps things up with additional machining enhancements — including the signature "AGENCY" port-side engraving — and a refined aesthetic finish, making it a great choice for shooters who want enhanced visual appeal alongside proven performance, with only a modest price difference over the Standard Line.
