This is a 5-sided flat fluted threaded barrel for the Glock 17 9mm, finished in a durable plum color. It’s for shooters looking for a reliable, match-grade barrel with suppressor compatibility, without adding significant weight to their carry setup. Since we started stocking it in late 2024, it has consistently been one of our top-selling barrels in its category.
Stand-Out Features
- 5-Sided Flat Fluting: Provides a unique aesthetic and aids in heat dissipation during extended range sessions.
- Threaded Muzzle: 1/2×28 threads allow for the direct attachment of compensators, muzzle brakes, or suppressors (with proper adapter).
- Match-Grade Construction: CNC-machined from 416R stainless steel for improved accuracy and consistent lockup.
- Plum PVD Finish: A durable, corrosion-resistant finish that offers a distinct look compared to standard black or stainless options.
- Minimal Weight Addition: As our staff noted after installation, the added weight is barely noticeable, coming in at under an ounce more than a factory barrel.

Your Questions Answered
Will this barrel fit my Polymer80 or other aftermarket frame?
Yes, this barrel is designed to fit standard Glock 17 spec slides and frames. It is compatible with most aftermarket frames, including Polymer80, that are built to Gen 1-3 Glock 17 specifications. Always ensure your slide’s internal dimensions are to spec for reliable function.
Is the finish durable?
The plum color is a Physical Vapor Deposition (PVD) coating applied over the stainless steel. It is highly resistant to wear, corrosion, and solvents, making it suitable for regular use. It will maintain its appearance far better than typical cerakote or paint finishes.
Do I need a thread protector?
While not strictly required for function, we recommend using a thread protector when a muzzle device is not installed. This prevents damage to the threads from debris or impact. Standard 1/2×28 protectors are widely available if one is not included with your purchase.
