Shrink split times and keep your dot flatter with the Agency Arms Gen3 Compensator (417-3-BLK). Purpose-built for 9mm Glock® Gen3 platforms, this premium comp uses a two-chamber design with two vertical ports and two side venting ports to redirect gas, cut muzzle rise, and reduce felt recoil—without the bulk. It ships ready to install with two set screws, an Allen wrench, and a vial of Rocksett® so you can secure the comp for hard use. A front sight hole gives you the option to relocate your front sight onto the compensator (where desired) for a longer sight radius or specialty builds.
Whether you’re tuning a carry-optic pistol, a duty-reliable blaster, or a match gun, the 417-3-BLK delivers Agency’s signature performance and clean, factory-grade fit.

Installation Notes (Read Before You Wrench)
Confirm Compatibility: 9mm Gen3 Glock 17/19/34 with threaded 1/2x28 barrel. (Not for Gen4/Gen5 unless using appropriate adapter/parts—verify before purchase.)
Test-Fit: Thread the comp fully by hand to ensure clean shoulder contact.
Rocksett® & Set Screws: Apply a small amount of Rocksett to the threads, time the comp, and snug the two set screws with the included Allen wrench. Allow Rocksett to cure per instructions (typically 12–24 hrs).
Function Check: Verify slide cycles freely and that the comp clears the frame/dust cover at full recoil.
Sights/POI: If using the front sight hole, install per sight manufacturer’s instructions; re-zero after any sight or ammo change.
Ammo Note: Comps perform best with full-power or +P 9mm loads; very soft ammo may reduce effect and reliability. Always verify function with your carry/training loads.
Ideal Use Cases
Concealed Carry/Defensive Training: Faster follow-ups and improved sight tracking under pressure.
Competition & Range: Cut splits on bill drills, transitions, and partials with less dot bounce.
Duty/Professionals: Enhanced control for high-tempo strings while maintaining a compact overall length.
Care & Maintenance
Carbon Management: Periodically soak/brush the ports and first chamber to remove carbon buildup.
Thread Care: When removing, heat or soak to soften Rocksett; avoid over-torqueing on re-install.
Inspect Screws: Check set-screw torque and witness mark them if you run high round counts.
Frequently Asked Questions
Q: Will this fit Gen4 or Gen5 Glocks?
A: This model is Gen3-specific. Some users run adapters or different barrels on later gens, but confirm fit before ordering.
Q: Do I need a threaded barrel?
A: Yes. The compensator requires a 1/2x28 threaded 9mm barrel (G17/G19/G34 length as applicable).
Q: Does it work with a weapon light?
A: Usually yes, but holster and light fitment varies. Ensure the comp clears your frame/light combo and test with your holster.
Q: Will it affect reliability?
A: Properly installed comps with appropriate ammo and recoil springs are reliable. If you run very light loads, consider tuning springs.
Q: What’s the front sight hole for?
A: It allows you to relocate the front sight to the comp, potentially lengthening sight radius and enabling certain sighting setups.
