Frequently Asked Questions
Will this barrel fit my Glock 19 Gen 3 or Gen 4?
This Agency Arms Mid Line barrel is specifically designed and tested for the Glock 19 Gen 5. While the external dimensions of Glock barrels are similar across generations, Agency Arms specs and fits this barrel to Gen 5 tolerances. For Gen 3 or Gen 4 compatibility, check Agency Arms' lineup for generation-specific models to ensure a proper fit and safe operation.
What suppressors or muzzle devices are compatible with the 1/2×28 threads?
The 1/2×28 thread pitch is the standard for 9mm pistol suppressors and muzzle devices in the United States. Most major suppressor manufacturers — including Silencerco, Dead Air, and Rugged Suppressors — offer 9mm cans threaded at 1/2×28, making this barrel broadly compatible. Always verify thread pitch with your specific suppressor or device before mounting. A thread protector is recommended when shooting without a device attached.
Does this barrel support +P or +P+ ammunition?
The 416R stainless steel construction and SAAMI-spec rifling make this barrel well-suited for standard 9mm and +P ammunition. However, Agency Arms does not explicitly rate this barrel for +P+ loads, and sustained use of +P+ can accelerate wear on both the barrel and pistol components. For regular defensive or range use with standard 9mm or occasional +P rounds, this barrel is an excellent choice.
