Most Helpful Positive Review Best barrel out there!
This is by far the best aftermarket barrel I have purchased. Perfect fit and finish! I'm happy with everything about this barrel. I used this to finish off my Polymer80 G19 build. I'll be buying more Faxon products going forward.
Most Helpful Negative Review Damaged Threads
I expected better quality control out of Faxon. The thread protector would only screw on for about 2 threads. They need to fire their QC person. I was going to ship it back for a replacement but Optics Planet wants to charge me for a return. Good thing I have gun smithing skills I will just rethread...

Much better accuracy

by John Whitney, Verified Owner from IN, United States Written on April 13, 2026
This is my second Faxon MATCH(not duty) barrel I have for my Glock 19s. Having finished building out my own G19, I put a $40 ported barrel to finish the build. It ran great but the accuracy using 115gr ammo was horrendous. Bench testing (having the front and the back resting on solid surfaces) the gun put groups at about 8-10 inches at 25yds. Knowing that I wasn't that bad of a shot I brought out my original G19 with my 1st Faxon barrel and the groups were 1-2 inches at 25yds using the same bench test as above.

I immediately ordered another threaded Faxon Match barrel and tested the results today. After dialing in the zero I got 2-3 inch groups at 25yds. I believe the barrel could do a bit tighter based of the natural mechanical wobble I had in my hands today.

Another interesting note is that when I first bought my original Faxon barrel it was $185, and now, they are around $100 for the same quality barrel. After contacting Faxon on this they said they had streamlined production and were able to pass the savings on to the customer.

Those looking to train with their handguns out to 25 yds and more, MUST FIRST confirm what the gun is capable of with the ammo you will be using. This will save you much frustration when shooting at greater distances with no consistency. This is very important.

Having shopped for every match barrel that exists on the market today I cannot think of any reason to buy a $200-$300 plus barrel when I am already getting 1-2 inch groups.

And, for all...

Facing Threaded barrel

by RKB, Verified Owner from CO, United States Written on January 22, 2026
Great barrel purchased to mount Banish 9 suppressor. Excellent guality barrel, works very well with suppressor. Barrel came with “o” ring on shoulder of barrel that allows tightening of suppressor to proper torque but then allows for easy removal. Great quality product, just make sure you clean it very well before using as it comes with very heavy coating of grease inside barrel.
Pros:
  • Great quality, rapid shipping as usual from
  • Great quality, rapid shipping from Optics planet
Cons:
  • None

Excellent Threaded Barrel

I purchased a Glock 19 Gen 4 (COMPACT) but needed a threaded barrel for it. The price for this one was great, the shipping was quick, and the barrel works fantastic. Hopefully this review will help someone else decide one way or the other... But if I were you, I'd pull the trigger and get it...

  • Works great with a Suppressor..
Cons:
  • None
Best Used for:
  • suppressed shooting
