Faxon EXOS-513 Pistol Compensator for Glock® Gen 3 & FX-19 – 9mm (1/2x28)

SKU: FF-P-A-COMP-DS-G-01  |  UPC: 816341026179  |  Caliber: 9mm  |  Thread: 1/2x28


Overview

The Faxon EXOS-513 is a platform-focused 9mm pistol compensator engineered for Glock® Gen 3 pistols and the Faxon FX-19 Hellfire. Machined from 6061 aluminum and finished in black anodize, the EXOS-513 uses a single-chamber design with uniquely angled ports to manage propellant gas in a way that reduces muzzle climb and felt recoil while supporting consistent cycling behavior.

Design Highlights

  • Angled port geometry redirects gas upward (not only sideways) to reduce up/down muzzle movement.
  • Single-chamber compensator design tuned around real pistol timing considerations.
  • Flush-fit profile designed to sit cleanly with the slide when paired with Faxon barrels.
  • Optimized barrel protrusion guidance: for non-Faxon barrels, a protrusion of 0.600" or less is recommended for a flush fit.

The EXOS-513 is designed and tested specifically for the following models:

  • Glock® 19 Gen 3
  • Glock® 17 Gen 3
  • Glock® 34 Gen 3
  • Faxon FX-19 Hellfire

Fitment Note: This compensator is engineered around the platforms listed above. Fitment with other pistols or generations is not guaranteed.

    Does what it says on the tin. havn't fired it yet but it looks cool. I can't imagine you are looking at this product for duty use. so im assuming its for looking cool and having fun and a little improvment for muzzel flip. for that. its great.

    Absolutely Worth It

    Posted by Capt1776 on Dec 20th 2024

    Easy to install, looks great, works like a charm. I had looked at a more expensive brand that included a barrel, but opted for Faxon because I like the barrel I have and didn't want to waste money on a proprietary comp/barrel system. I've used Faxon rifle barrels in the past and know that their products are top notch so the decision was easy. If you're planning of shooting fast and accurately, this comp is the way to go....along with lot's of practice obviously.

    Excellent Comp

    Posted by Steve W. on Apr 5th 2022

    The finish is very nice, and it fits flush on my Palmetto State Armory Dagger. Glad I ordered! I'll be ordering the Exos comp for the P365XL soon! Thanks Faxon!

    Great compensator

    Posted by JD on Mar 28th 2022

    I finally had a chance to get to the range again since installing this and I was very happy with how it felt. This is not the first compensator I have tried on my PF940c but it will be the one that stays on it for good now. The main reason I switched is because the previous one would catch on the ALS on my Safariland holster when drawing. This one does not catch at all. Installation was easy and did not take long at all.

    Exos Comp on P80 G19 Build

    Posted by Michael Phillip McEachern on Dec 23rd 2021

    This thing is beautiful and an absolute breeze to install. 5 star rating based on that, haven’t tried her out yet. Looks great with my slide from US Patriot Armory. Went cheap with shipping and still arrived in a week. Will update review after 9mm range day!
