Frequently Asked Questions
Will the Agency Arms 417 Comp work with my factory Glock barrel?
No — the 417 Compensator requires a threaded barrel with a 1/2x28 thread pitch, as factory Glock barrels are unthreaded. You will need to install an aftermarket threaded barrel (such as those offered by Agency Arms, Lone Wolf, or ZEV Technologies) before mounting this comp. Once paired with a compatible threaded barrel, it works with your stock Gen 4 recoil spring assembly.
Is this compensator compatible with Gen 3 or Gen 5 Glock pistols?
This specific version of the 417 Comp is designed for Glock Gen 4 pistols (G17, G19, G34). Agency Arms produces generation-specific variants, so it's important to select the correct model for your pistol's generation. Using a Gen 4 comp on a Gen 3 or Gen 5 firearm may result in fit or function issues.
Will adding a compensator affect the reliability or cycling of my Glock?
The Agency Arms 417 Comp is specifically designed to function with the OEM Glock recoil spring assembly, minimizing reliability concerns. However, as with any compensator, ammunition selection matters — lighter or underpowered loads may cause cycling issues. Standard pressure (NATO spec or equivalent) 9mm ammunition is recommended for the most consistent cycling performance with this comp installed.
