Overview

The Faxon EXOS-543 pistol compensator is designed for Glock® Gen 4 9mm platforms to improve shooting consistency through controlled gas redirection. Machined from 6061 aluminum and finished in black anodize, the EXOS-543 uses a single-chamber design with uniquely angled ports to help reduce muzzle climb and manage felt recoil while supporting stable cycling on properly configured hosts.

  • Glock® 19 Gen 4
  • Glock® 17 Gen 4

    I’ve put thousands of rounds through my Glock 17. If I knew this is what a comp did, I’d have purchased one long time ago! Awesome product!

    OUTSTANDING!

    I have this on a GST9 build, with a Trybe barrel, and a GST9 “WREATH” slide. Not only does it look wicked…. The functionality is second to none. Compared to the Strikeforce compensator…. Well it doesn’t even compare.

    Installed on a Shadow Systems MR920 War Poet and it looks outstanding!! I have only been able to put about 30 rounds through it so far, but it seems to really help mitigate the felt recoil! I love it! It's amazing, especially at this price point! I was hoping to be able to upload a couple of pictures here but I don't see that option.
