Threaded Glock Barrels questions

What thread pitch do Glock threaded barrels use?

Most 9mm models, including the 17, 19, 26 and 43, use 1/2x28 threads. The .45 ACP Glock 21 threaded barrel uses the larger .578x28 pitch instead of the standard 9mm pitch.

Is a thread protector included?

No, thread protectors are sold separately from the barrel itself. Choose one sized to match your barrel's thread pitch, either 1/2x28 or .578x28 depending on caliber.

Are threaded barrels legal to buy and install?

Rules vary by state and locality and can change over time. Check federal, state and local law before ordering or installing a threaded barrel on your pistol.
