If you're running a suppressor on your Glock 34, the SilencerCo AC860 threaded barrel is engineered to get you there. This 9mm barrel drops into your Gen 3 or Gen 4 Glock 34, replacing the factory barrel with a precision-machined unit ready for the suppressor attachment you've already invested in. At 5.8 inches long, it maintains the Glock 34's competitive slide length while adding the 1/2x28 threads that match the vast majority of 9mm suppressor mounts. Whether you're prepping for subsonic drills, reducing signature at the range, or just dropping decibels for hearing protection, this barrel lets you do it without swapping guns or jerry-rigging solutions.
Built from 416R stainless steel, the AC860 delivers the durability you need in a precision firearm component. It comes finished and ready to install—no guessing about material or longevity. The barrel includes a thread protector, so your threads stay clean until you thread on a suppressor. Installation is straightforward: field strip your Glock, swap the barrel, and you're good to run. No gunsmithing required.
The Glock 34 is already a favorite for competitors and serious shooters who want velocity and sight radius. Pair it with a suppressor-ready barrel and you've opened up new possibilities for training, matches, and recreational shooting without the concussion that wears on your ears and shooting buddies downrange.

Frequently Asked Questions
Will this barrel fit my Glock 34?
Yes, the AC860 is designed specifically for Glock 34 frames in Gen 3 and Gen 4. Confirm your frame generation before ordering.
What suppressors will thread onto this barrel?
The 1/2x28 thread pitch is the standard for most 9mm suppressors. Your suppressor must be rated for 9mm and have 1/2x28 female threads to mount. Check your suppressor specs or consult with your suppressor manufacturer if you're unsure.
Do I need a gunsmith to install this?
No. The AC860 is a field-strippable drop-in replacement. Remove your factory barrel and install the threaded barrel using the same steps as a normal Glock breakdown. No specialized tools required.
What's included in the box?
The barrel comes with a thread protector to keep the threads clean and protected until you attach a suppressor.
