Threaded 9mm drop-in barrel for Glock 17 Gen 1-4. Slides into factory and aftermarket Glock 17 slides with no fitting or hand-lapping. The 1/2x28 muzzle accepts standard 9mm compensators, suppressors, and thread protectors. Not compatible with Gen 5 frames — the Gen 5 barrel and recoil-rod geometry are different.
Machined from 4150 chromoly steel with a black nitride finish that resists corrosion, holds oil, and doesn't chip like Cerakote around the muzzle threads. 1:16 twist stabilizes standard 115–147gr 9mm loads.
Micro Comp pairing: threads match the 3CR Tactical 9mm Micro Compensator (SKU 3CRGC01) — sized for full-frame G17/G19/G26 slide width. Suppressor use: torque any thread mount to spec and verify baffle-strike clearance before firing suppressed. Break-in: run 100–150 rounds before installing a comp for the first time so the barrel/lug interface seats fully.
