True Precision Glock 19 Threaded Barrel – Black Nitride QPQ

Looking to upgrade your Glock 19 with unmatched durability, sleek aesthetics, and true performance gains? The True Precision Black Nitride QPQ Threaded Barrel is engineered for shooters who want the very best — no compromises.

This drop-in threaded barrel fits Glock 19 Gen 1–5 and is precision-machined from certified USA 416R stainless steel. It features a QPQ (Quench Polish Quench) Black Nitride finish, also known as Melonite, that penetrates deep into the steel for extreme surface hardness, corrosion resistance, and a non-reflective black tone that won’t wear down like surface coatings.

The broach-cut 6-groove rifling supports both lead and jacketed ammo, while the 1/2x28 threads allow easy pairing with suppressors and compensators. Whether you're building out a carry gun, competition setup, or suppressor host, this barrel performs.
