Lakeline Ported Barrel Taurus GX4 Gold TiN - 9mm | ShopTaurus

Tame the muzzle rise on your micro-compact 9mm. The Lakeline LLC Ported Target Barrel (SKU: T-PT-GX4-246-TIN) is a premium, drop-in 416R stainless steel upgrade treated with an ultra-slick, wear-resistant Gold Titanium Nitride (TiN) finish.

Micro-compact pistols are highly convenient to carry, but their lightweight frames can produce a snappier recoil impulse. Take your shooting speed and precision to a whole new level with the Lakeline LLC Ported Target Barrel. Fully designed and manufactured in-house in Houston, Texas, by the veteran-owned team at Lakeline LLC, this is a premium, match-grade drop-in upgrade engineered specifically for the Taurus GX4 platform.

Constructed from gun-barrel-quality 416R stainless steel, this barrel extends roughly 1/4" past the front of the factory slide assembly. This extra length houses twin top-facing exhaust ports that capture expanding propellant gases and redirect them upward as the bullet exits the bore. The downward gas pressure counteracts muzzle flip, allowing you to track your sights through fast follow-up strings. With precision cut-rifling in an optimized 1:10 twist rate, an 11-degree target crown, and an elite, friction-reducing Gold Titanium Nitride (TiN) hard coat, this barrel dramatically improves both mechanical accuracy and corrosion protection.

Storefront Frequently Asked Questions

Q: Do I need to make any modifications to my factory slide to use this ported barrel?

A: No modification is required. This barrel drops directly into your factory Taurus GX4 slide assembly. The exhaust ports are located on the portion of the barrel that extends roughly 1/4 inch past the muzzle end of the slide, allowing gases to vent upward safely without damaging your slide.

Q: Will the gold finish wear off during heavy shooting sessions?

A: Titanium Nitride (TiN) is an incredibly hard, ceramic-like coating used on industrial cutting tools. While all moving metal-on-metal parts will eventually show minor "burnish" marks or friction tracking at contact points (which is completely normal), TiN holds up significantly better to abrasive wear, heat, and carbon build-up than standard factory bluing.

Q: Can I shoot standard target and defensive ammo through this barrel?

A: Yes, the chamber is cut to strict SAAMI dimensions and is designed to run standard factory 9mm Luger loads safely.
