Drop-in 9mm replacement barrel for Glock 17 Gen 3-4 frames. Machined from 4150 chromoly steel and finished in titanium nitride (TiN) — gold satin sheen, hardened surface, low-friction face for cleaner cycling and easier carbon removal between range trips.

Cut for 1/2x28 muzzle threads to accept standard 9mm compensators, suppressors, and thread protectors. Ships with a flush crown for clean use without a muzzle device installed.

Features:

• Fit: Glock 17 Gen 3-4 frames, 9mm
• Material: 4150 chromoly steel
• Finish: TiN (titanium nitride), gold satin
• Bore: 9mm Luger, 1:16 twist
• Length: full-length OEM profile
• Muzzle: 1/2x28 threaded, flush crown cut
• Drop-in fit — no fitting or gunsmithing required
• Thread protector not included

Pairs with the 3CR Tactical 9mm Micro Compensator and any 1/2x28 9mm muzzle device. Verify your slide is a Glock 17 Gen 3-4 pattern before install — Gen 5 lockup geometry differs and is not guaranteed to fit. Confirm headspace by hand-cycling a dummy round before live fire.
