FAQs – Glock 19 Gen 4 Barrels
Q: Are Gen 4 barrels compatible with Gen 3 or Gen 5 Glocks?
A: No. Due to differences in the locking lug and recoil spring system, Gen 4 barrels are not cross-compatible with Gen 3 or Gen 5 models.
Q: What thread pitch is used for threaded barrels?
A: All threaded options use 1/2x28 TPI, the standard pitch for 9mm suppressors and muzzle devices.
Q: Can I install a new barrel myself?
A: Yes. These barrels are drop-in — just field strip your Glock and swap in the new one.
Q: Is a threaded barrel legal in my state?
A: Most states allow threaded barrels, but some jurisdictions restrict them. Always check your local laws.
Q: What’s the best barrel for concealed carry?
A: Non-threaded, black nitride or DLC-coated barrels are ideal for EDC due to their durability and low reflectivity.
