Glock 20 Barrels – Threaded & Match-Grade Options for Gen 3–5

Upgrade your Glock 20 for unmatched precision and durability. Whether you use your 10mm Glock for hunting, range time, or tactical carry, a high-quality barrel makes all the difference. We offer threaded and flush crown Glock 20 barrels, all precision-machined for a drop-in fit with no gunsmithing required.

Why Upgrade Your Glock 20 Barrel?

Stock Glock barrels are functional, but upgrading to a match-grade barrel improves accuracy, consistency, and reliability. With tighter tolerances and premium finishes, you’ll notice a difference whether you’re firing standard 10mm ammo or custom loads.

  • Drop-in fit – no modifications required
  • Threaded options (1/2x28) for compensators or suppressors
  • Durable finishes: Black Nitride, TiN Gold, Stainless Steel
  • Compatible with Gen 3, 4, and 5 Glock 20 models

A match-grade barrel is machined to tighter tolerances than OEM, delivering improved accuracy and consistent performance with various 10mm ammo types.
