Threaded vs Non-Threaded – Which Should You Choose?

Choose a threaded barrel if you plan to run a suppressor or compensator. Prefer a flush-cut, non-threaded barrel for a sleek EDC setup or compliance with local laws. Both types are drop-in ready and offer improved performance over OEM barrels.

FAQs – Glock 19 Gen 3 Barrels

Q: Will these barrels fit Gen 4 or Gen 5 Glock 19s?
A: No. These are specifically designed for Gen 3 Glock 19 frames. Gen 4 and Gen 5 models require different locking lugs and geometry.

Q: What thread pitch is used for the threaded barrels?
A: All threaded models use 1/2x28, the standard pitch for 9mm suppressors and muzzle devices.

Q: Can I install this barrel myself?
A: Yes. These are drop-in barrels — simply remove your factory barrel during a field strip and replace it with the new one.

Q: Is a threaded barrel legal in my state?
A: In most states, yes. However, check your local laws, as some areas restrict threaded barrels due to suppressor compatibility.

Q: What’s the best barrel finish for everyday carry?
A: Black nitride and DLC are both great choices for EDC — they’re durable, low-reflective, and wear-resistant.
