Agency Arms 417 Gen 5 Single Port 9mm Pistol Compensator Black - 417S-G5-BLK
Product Description
Controlling muzzle flip on high-velocity 9mm duty pistols usually requires a tradeoff between flat-shooting performance and carrying convenience. Standard multi-port muzzle devices often add excessive length and mass, turning a practical concealed carry or duty setup into a cumbersome competition rig. The Agency Arms 417 Single Port Compensator solves this operational challenge by packing massive gas-redirection efficiency into a compact, ultra-streamlined profile designed specifically for Gen 5 Glock platforms. It delivers flat, neutral tracking without adding unnecessary bulk to your weapon's muzzle profile.
Machined from premium 7075 aluminum billet—a material offering significantly higher tensile strength and fatigue resistance than standard 6061 alloys—this compensator is built to endure the extreme blast pressures of high-volume defensive training. It features a rugged MIL-A-8625 Type 3 Hard Anodize matte black finish that matches the dark aesthetic of factory and aftermarket slides. A key engineering hallmark of the 417 series is its integrated front sight hole, which allows shooters to remove their front sight from the slide and press-fit it directly onto the top of the compensator. This turns your front sight into a stationary tracker that remains fixed during the slide cycle, drastically accelerating your sight recovery between shots.
In operation, the single vertical venting port channels expanding pressurized gases directly upward as the bullet leaves the muzzle crown. This downward force acts as an automatic counter-weight to natural muzzle rise, transforming snappy vertical lift into a soft, linear push directly back into the palm of your hand. Threaded to the industry-standard 1/2x28 pitch, the 417 block fits tightly against the slide face for a clean, integrated appearance. By leveling out the weapon’s recoil impulse, it allows your red dot or iron sights to stay pinned within your field of view during rapid-fire strings, giving you the tracking confidence needed for critical target transitions.
*Armorer Bench Notes & Technical Maintenance Guidance: The Gen 5 417 single-port model requires an optimal threaded barrel protrusion length of 0.715 inches (± 0.005") from the slide face to achieve a flush, gap-free fit. Be aware that aftermarket barrels from AlphaWolf, SilencerCo, Fortis, and Faxon may feature non-standard thread lengths that alter this clearance. For proper assembly, degrease the barrel threads and internal compensator threads completely before applying the included Rocksett compound to the two underside set screws. Torque the set screws evenly using the provided Allen wrench. Because compensators vent gasses that otherwise drive slide velocity, you may experience short-cycling with under-powered 115-grain plinking ammunition; for standard training, we recommend running hot NATO-spec 124-grain or 147-grain duty loads, or tuning your setup with a captured guide rod and a reduced-power recoil spring if necessary.
