True Precision
The True Precision 9mm Gold Threaded Barrel with Protector is a domestic-made upgrade for Glock 17 Gen 1–4 pistols designed with personal defense and suppressor-ready capability in mind. Built in Georgia by a team of skilled craftspeople committed to American manufacturing, this barrel threads on a standard 1/2x28 pattern, making it compatible with most common suppressor mounts and flash hiders. The 1:10 left-hand twist rifling is engineered for reliable 9mm Luger performance, and the included protector helps shield the threads when the barrel isn't in use.
True Precision's reputation rests on precision engineering and materials sourced and finished right here in the USA. Rather than cutting corners with offshore suppliers, they machine and QC every part themselves, which translates to tighter tolerances and more consistent performance than many mass-produced alternatives. If you're building or refreshing a Glock 17 with suppressor compatibility in mind, or you simply want a higher-quality barrel than OEM, this threaded option gives you the upgrade without the guesswork.
The gold finish isn't just cosmetic—it's a sign of the attention to detail that goes into each piece. Whether you're a serious handloader, suppressor owner, or someone who prioritizes American-made components, this barrel checks the boxes for reliability and domestic manufacturing.
| Caliber | 9mm Luger |
| Thread Pattern | 1/2x28 |
| Rifling Twist | 1:10 (left-hand) |
| Fit | Glock 17 Gen 1, 2, 3, 4 |
| Finish | Gold PVD |
| Manufacture | USA |
Yes—it's designed specifically for Glock 17 Gen 1 through Gen 4 models. If you have a Gen 5 or a different Glock platform, this barrel won't fit.
The 1/2x28 is a standard thread pitch for 9mm suppressors and muzzle devices. Most common 9mm cans and brakes are compatible, but always verify your specific suppressor's specs before purchase.
Yes, the barrel comes with a protective cap to cover the threads when the barrel isn't mounted with a suppressor or brake.
Left-hand twist is simply True Precision's design choice for 9mm performance; it performs reliably with standard 9mm Luger ammunition. Twist direction alone doesn't affect reliability or accuracy in 9mm if the barrel is properly fitted to your gun.
