🧠 Glock 34 Barrel – Frequently Asked Questions

Q: Will this barrel fit a Gen 5 Glock 34?
A: Yes — if the product is labeled Gen 5 compatible. Gen 5 barrels use a revised locking lug and must be matched correctly.

Q: Can I use this barrel with a suppressor or compensator?
A: Absolutely. Threaded models use a 1/2x28 thread pitch, the most common standard for 9mm muzzle devices.

Q: Is the barrel drop-in or will I need to fit it?
A: All of our Glock 34 barrels are drop-in fit for the correct generation. No gunsmithing required.

Q: Which finish is most durable?
A: Black Nitride offers exceptional corrosion resistance. TiN (gold) adds both visual appeal and a hard, smooth surface for friction reduction.
