John Whitney's Review of Faxon Firearms EXOS-543 Pistol Compensator for Glock Gen 4 19/17/34

I waited a while to write this review because I wanted to give an actual review on how this comp performed after putting 1-2k rounds through
it.
I ran this comp on my Glock 19 Gen 4 with a Faxon 416R threaded barrel. All else on the gun is stock.
The first time I fired my Glock 19 with the compensator on, I could tell an immediate difference. It absolutely levels the gun out and reduces
muzzle flip notably. How anyone debates if a compensator does, or does not, affect the muzzle flip on a 9mm is ridiculous. It absolutely does. It
does make for better recoil management and faster split times (if you are using a timer).
I also wanted to touch on the reliability of a Glock 19 when running a compensator. Before buying a compensator, I had seen several videos
talking about compensators making a Glock, or any other pistol, less reliable. This ‘can’ be true, but in reality, is not a factor. I personally have
full confidence in the reliability of my Glock and I conceal carry it all the time WITH the compensator on. People looking to buy this
compensator will need to test various ammo out to see what makes the gun reliable and unreliable. For me I exclusively run 115gr both for
training and defense ammo. Through training I found that 115gr ammo that has LESS than 1100fps will begin to cause malfunctions after 100-
200 rounds through a freshly cleaned and oiled pistol. To correct the gun’s reliability, I do not stock any training ammo that has less than
1100fps muzzle velocity. 9mm 115gr 1100fps+ ammo is more than readily available for cheap prices. The defense ammunition I run is 1300fps
Corbon 115gr. I have ran 500+ rounds through the gun without cleaning it with 1100fps + ammo with absolutely no problems whatsoever. I
have done this 3-4 times and cleaned and oiled the gun after 500 rounds. The reliability issue is a moot point if you have the correct powered ammo. Hopefully, this review will help those on the fence on whether to buy this compensator or not.
