If you've got a P320 and you're chasing flatter shooting and quicker target reacquisition, the Faxon EXOS-515 is built to do exactly that. The compensator works by venting expanding gases upward rather than just sideways, which reduces the vertical muzzle movement that throws your sights off target. This single-chamber design is engineered around real-world pistol dynamics so you get consistency improvements without major reliability concerns.
The EXOS-515's key feature is those angled front ports. When you fire, gas that would normally be lost is redirected upward at the muzzle. This pushes the gun's nose down while recoil tries to push it up, effectively canceling out some of that rise. The result is a flatter sight picture and less time spent getting back on target between shots. You'll notice the improvement most on rapid fire drills and double taps where every millisecond counts.
Faxon machined this compensator from 6061 aluminum and finished it in black anodize for corrosion resistance. It's lightweight at 0.8 pounds and measures 1.4 inches overall length. The 1/2×28 threading is the standard for 9mm pistols. Installation is straightforward with the included thread locker, two 6-32 set screws, and 1/16 inch Allen wrench. The compensator is optimized for Faxon barrels but will work with other brands as long as the barrel protrusion is 0.600 inches or less for a flush fit.
This compensator works best with the P320 Full-Size platform, which Faxon has tested extensively. Compatibility with P320 Compact or Carry models is possible but wasn't the primary focus during testing. Like any compensator, it may require minor tuning of lubrication or ammunition selection depending on your specific setup, so plan to put a few magazines downrange to dial everything in.
The EXOS-515 was tested and confirmed for the P320 Full-Size. While it may be compatible with Compact and Carry variants, that testing wasn't done as the primary focus, so fitment cannot be guaranteed. Check with the manufacturer if you're running a non-Full-Size model.
The EXOS-515 is optimized for Faxon branded barrels. If you're using a different brand, make sure the barrel protrudes 0.600 inches or less for a flush fit with the slide. This measurement is important for both aesthetics and compatibility with many holsters.
Most shooters don't need to change springs, but some tuning may be necessary depending on your ammo type and lubrication. Compensators can affect bolt cycling timing, so you might need to experiment with different ammunition or adjust your maintenance routine after installation. Plan to shoot a few magazines to break it in.
The EXOS-515 reduces muzzle climb through upward gas deflection, giving you a flatter sight picture and faster follow-up shots compared to an uncompensated barrel. The actual improvement varies based on ammunition, technique, and pistol setup, but the angled port design is engineered to maximize these benefits in real-world shooting conditions.
