True Precision threaded barrel for Glock 19 Gen 1-5 — a match-grade drop-in upgrade in a black DLC finish for shooters running a suppressor or muzzle device on a Gen 1-5 G19.

Features:

• Fits Glock 19 Gen 1-5 in 9mm Luger (also Glock 19X and Glock 45)
• Material: certified 416R stainless steel billet
• Broach-cut 6-groove match-grade rifling, 1:10 RH twist
• Improved chamfers, radius cuts, and lockup geometry over OEM
• Fully supported SAAMI-spec chamber — runs hollow-points, FMJ, and cast lead
• 1/2x28 muzzle threads with Viton O-ring locking thread protector included
• Finish: black diamond-like carbon (DLC)
• Drop-in fit — no gunsmithing required

Finish note: DLC will show high-wear marks at the locking lug face and barrel hood over time — this is normal and does not affect function or accuracy.

Hand-cycle a few dummy rounds to confirm headspace and feeding before live fire. If shooting suppressed, verify recoil-spring weight per your host pistol.
