FAQ

Q: Will a Glock 17 Gen 3 barrel fit a Gen 4 or Gen 5 slide?
A: No. Glock 17 Gen 3 barrels are not compatible with Gen 4 or Gen 5 frames due to different locking lug and recoil system designs.

Q: Are these barrels suppressor-ready?
A: Yes. Threaded options feature a standard 1/2x28 thread pitch for 9mm suppressors and compensators.

Q: Do I need a gunsmith to install a Glock 17 Gen 3 barrel?
A: No. These barrels are drop-in ready and require no fitting or modifications when paired with a compatible Gen 3 slide.

Q: What’s the difference between TiN and Black Nitride finishes?
A: TiN (Titanium Nitride) offers a gold-colored, extremely hard, corrosion-resistant surface. Black Nitride is a darker, more subdued finish with excellent wear resistance.

Q: Are match-grade barrels more accurate than factory barrels?
A: Yes. Match-grade barrels typically offer tighter tolerances and improved rifling for better groupings.
