For G34

Faxon Barrels for Glock® 34

8 drop-in 9mm barrels for Glock® 34 Gen 2, Gen 3, and Gen 4 slides and Glock® 34 Gen 5 and Gen 6 slides: 4 Duty Series ($102–$104) and 4 Match Series ($120–$131), threaded and non-threaded, made in Greater Cincinnati, Ohio. Faxon makes separate G34 Gen 2–4 and G34 Gen 5–6 barrels, so order the one for your generation. Every Faxon pistol barrel starts as a long blank that Faxon button rifles 1:10 with six grooves (land and groove, not polygonal, so cast lead is fine), air gauges, and stress relieves in-house, then qualify-turns and mills into a barrel that drops into a factory-spec slide with no gunsmithing. Every barrel is checked for burrs under 10x magnification and its hood is run through a go/thru gauge. Duty Series barrels are 4150 CMV with salt-bath QPQ nitride inside and out. Match Series barrels are 416-R stainless, heat treated for pistol-barrel hardness, with Faxon fluting and black nitride or PVD finishes (TiN, Chameleon, Nickel). Threaded barrels are 1/2x28 and include a thread protector; threaded barrels can’t ship to California. Owners rate them 4.9 out of 5 stars across 13 reviews on FaxonFirearms.com.

All G34 barrels are 9mm, 1:10 twist, six-groove button rifled, with a SAAMI 9mm chamber and target crown.

Threaded Barrels, Comps, and Suppressors

Every threaded Faxon G34 barrel is cut 1/2x28, the common 9mm thread, and ships with a thread protector. Faxon EXOS® compensators are built for each slide: EXOS-513 for Glock® Gen 3, EXOS-543 for Glock® Gen 4, EXOS-553 for Glock® Gen 5. Thread locker comes with the comp; use it on the barrel’s muzzle threads only, not on the set screws. Running a suppressor usually calls for suppressor-height sights. Threaded barrels cannot be shipped to California.

  4. Stress relieved in-house after rifling, just like Faxon rifle barrels
  5. Blank cut to length and qualify-turned true to the bore
  6. Hood, lugs, profile, SAAMI 9mm chamber, and target crown turned and milled; threaded barrels cut 1/2x28
  7. 416-R Match Series barrels heat treated to pistol-barrel hardness
  8. Salt-bath QPQ nitride or PVD finish
  9. Every barrel checked for burrs under 10x magnification and its hood run through a go/thru gauge
  10. Laser-marked and final inspected

G34 Barrel FAQs

Do I need a Gen 2–4 or a Gen 5–6 barrel?

Pick by your slide’s generation. Faxon makes separate G34 barrels for Gen 2–4 slides and for Gen 5 and Gen 6 slides; each row above names its generation.

Will a Gen 5 barrel fit my Gen 6?

Yes. G34 Gen 5 barrels from Job #16477 on, engraved on the non-ejection side of the hood, include the Gen 6 relief cut and fit the Glock® 34 Gen 5–6.

Are Faxon pistol barrels drop-in?

Yes. They are direct replacements for the factory barrel in factory-spec slides, with no gunsmithing. Some aftermarket slides may need minor fitting; check each product page for compatibility notes.

Can I shoot cast lead?

Yes. Six-groove button rifling is land-and-groove rifling, not polygonal, so Faxon pistol barrels run jacketed and cast lead bullets.

What is the difference between Duty Series and Match Series?

Duty Series barrels are 4150 CMV in an OEM-style profile with salt-bath nitride inside and out. Match Series barrels are 416-R stainless, heat treated for pistol-barrel hardness, and come in fluted profiles with nitride or PVD finishes.

Do threaded barrels include a thread protector?

Yes. Every threaded Faxon pistol barrel is cut 1/2x28 and ships with a thread protector. Threaded barrels cannot be shipped to California.

Do I need an FFL?

No. Pistol barrels ship directly to you.

Where are Faxon pistol barrels made?

In Greater Cincinnati, Ohio.
