The Lantac 9INE Glock 19 9mm Luger 4.01" stainless steel fluted threaded barrel is a match-grade drop-in replacement for Gen 3 and Gen 4 Glock 19 pistols. Built from 416R stainless steel—the industry standard for precision barrels—this barrel transforms your carry or duty gun into a tighter, more accurate platform without requiring any gunsmithing. Lantac's proprietary machining process holds tolerances to ±0.0002", delivering the consistency you need whether you're running drills at the range or relying on your pistol for serious work.
The 9INE's real edge is in the details. The barrel features Lantac's proprietary flute pattern, which reduces weight and helps manage heat during extended shooting sessions. The 1/2x28 right-hand threaded muzzle gives you mounting options for suppressors or muzzle devices. The bore itself is double-honed to a maximum roughness average of 12 microinches, and the SAAMI-spec chamber is precision-cut and polished to 16 RA—meaning you get smooth feeding and reliable extraction cycle after cycle. The satin stainless finish resists corrosion, critical for a gun that might see duty in variable conditions.
This is a straightforward upgrade: remove your factory barrel, drop in the 9INE, and you're done. No fitting, no headspace worries. Lantac machines each barrel from pre-hardened 416R stainless, stress-relieves it to their proprietary spec after rifling, then stress-relieves again after final hardening to 38–42 Rockwell C. The result is a barrel that holds zero and shoots tighter groups without the brittleness that can come from aggressive hardening. If you run your Glock hard and want accuracy without the gunsmith visit, this is the barrel to run.
| Caliber | 9mm Luger |
| Barrel Length | 4.01" |
| Material | 416R Stainless Steel |
| Finish | Satin/Bead Blasted |
| Rifling | 6 groove, cut rifled, right hand |
| Twist Rate | 1:10 |
| Thread Pitch | 1/2x28 RH |
| Chamber | SAAMI Specification |
| Bore Finish (RA) | 12 microinches maximum |
| Chamber Finish (RA) | 16 microinches maximum |
| Hardness | 38–42 Rockwell C |
| Dimensional Tolerance | ±0.0002" |
| Compatibility | Glock 19 Gen 3 and Gen 4 |
Yes. The Lantac 9INE is a true drop-in replacement for Glock 19 Gen 3 and Gen 4 models. Remove your factory barrel, install the 9INE, and you're ready to shoot. No fitting, headspace work, or trips to a gunsmith needed.
The 9INE features a 1/2x28 right-hand threaded muzzle, the standard pitch for 9mm suppressors and muzzle devices. You can thread on any compatible suppressor or brake.
416R is the industry standard for match-grade barrels. It offers excellent corrosion resistance, high tensile strength, and superior machinability, which allows Lantac to hold the tight ±0.0002" tolerances that improve accuracy. The barrel is stress-relieved to Lantac's proprietary specification to ensure consistency and durability.
Yes. The tighter tolerances, match-grade chamber, and precision bore improve accuracy and reliability, making it well-suited for carry, duty, or range use. The satin stainless finish also resists corrosion in variable conditions.
