Frequently asked questions
What is Agency Arms known for?
Agency Arms is best known for custom Glock triggers, match grade barrels, and full custom pistol builds. The company built its reputation on hand fitted trigger work and slide modifications that reduce pre-travel and reset distance compared to factory Glock parts, and it has since expanded into build services for Sig P320, M&P, and FN pistols.
Are Agency Arms triggers worth the price?
Most reviewers and owners report a noticeably cleaner, more consistent trigger pull compared to a stock Glock trigger, with a shorter reset and reduced pre-travel. Independent testing has measured meaningfully lighter, more consistent pull weights than factory triggers. The Syndicate line offers a lower cost entry point, while the Premier drop-in triggers are aimed at shooters who want the most refined feel.
Where is Agency Arms located?
Agency Arms is headquartered in Caldwell, Idaho. The company was originally based in Ventura and Camarillo, California, before relocating its corporate operations to Idaho.
What pistols does Agency Arms build for?
Agency Arms offers parts and build services for Glock, Sig Sauer P320, Smith & Wesson M&P, FN 509, Benelli shotguns, and the Springfield Prodigy. Glock remains the platform with the widest range of Agency Arms parts and complete build options.
How much does a full Agency Arms custom Glock build cost?
Pricing depends on the scope of work. A single drop-in trigger typically runs under $200, while a full custom build with slide work, frame work, a compensator, and an optic cut can run into the thousands of dollars depending on the parts and finish selected. Buyers should request a current quote directly from Agency Arms or an authorized dealer, since pricing changes with parts availability.
Is Agency Arms a gun manufacturer or a customizer?
Agency Arms operates as both. The company manufactures its own aftermarket parts, including triggers, barrels, slides, and compensators, and it also performs custom build services on customer-owned or dealer-sourced pistols. Agency Arms is registered as a firearms manufacturer and sells both individual parts and complete custom builds.
