The Faxon EXOS-513 Pistol Compensator for the Glock G19 is a purpose built muzzle upgrade that tames recoil and muzzle flip on compact Glock platforms. It is CNC machined from high strength 6061-T6 aluminum and protected by Type III hardcoat anodizing, keeping added weight at the muzzle low while standing up to hard use. This is the part that makes a compact pistol shoot like a bigger one.
Muzzle rise is what slows your splits. Redirect the gas and the sights come back faster.
What the Faxon EXOS-513 Pistol Compensator Does
The three port design does the real work. A top port and dual side ports redirect gas to counteract muzzle rise and soften the recoil impulse, delivering a flatter shooting pistol and faster recovery between shots. That translates directly into quicker follow ups in competition, cleaner reps in training, and more control when it matters most.
This is for the competitor shaving tenths off a stage, the trainer running high volume drills, and the G19 owner who already has a threaded barrel and wants more out of it. It is also a smart choice for shooters who find a compact 9mm snappy and want a calmer gun without adding a full size slide. The improvement is immediate and obvious on the first magazine.

Specifications and Why They Matter
The 6061-T6 aluminum construction is a deliberate choice. Steel compensators add weight exactly where you least want it on a compact pistol, while aluminum gives you the gas management without turning the muzzle into a pendulum. Type III hardcoat anodizing is the hardest common anodize, and it is what keeps carbon and cleaning chemicals from eating the finish.
The port layout is the functional heart of the Faxon EXOS-513 Pistol Compensator design. Gas directed upward through the top port pushes the muzzle down against rise, while the dual side ports balance the pistol so it does not twist in the hand. Three ports is enough to feel without turning the pistol into a flash and blast machine at an indoor range.
The 1/2×28 thread pitch means this compensator fits the standard threaded 9mm barrel, so it works on your existing setup. Set screws and thread locker are included, which is the correct way to keep a compensator indexed and clocked correctly under recoil.
Installation, Use, and Care
Installation is straightforward on any standard 1/2×28 threaded barrel using the included set screws and thread locker, with no gunsmith required. Thread it on until it seats, index it so the top port faces true vertical, then lock the set screws down. Check the screws again after your first fifty rounds, since the Faxon EXOS-513 Pistol Compensator sees real gas pressure on every shot.
Expect a change in behavior on the range. Re zero your sights, because a compensator shifts point of impact, and give yourself a few magazines to adapt your grip to the flatter recoil. Some ammunition drives a compensator better than others, so try a couple of loads and pick the one that tracks best for you.
Carbon builds up quickly inside the ports, so soak and brush them during normal cleaning rather than letting deposits harden. Avoid abrasives that will scar the anodizing. Faxon optimized the EXOS-513 around its own match grade Glock 19 barrels, and the refined fit on compact builds keeps the profile clean and snag free.
If your G19 already wears a threaded barrel, this Faxon compensator is one of the easiest performance upgrades you can bolt on, and you will find the rest of the supporting gear in our Apparel and Gear collection. Ships direct to your door, no FFL required.
