Give your single-stack G43 a precision upgrade built for accuracy, reliability, and daily carry durability. The True Precision 3.40" 9mm barrel for Glock 43 is CNC-machined from 416R stainless steel—the benchmark steel for match pistol barrels—then finished in a tough black, low-glare coating that resists sweat, corrosion, and holster wear. Designed as a true drop-in part, it tightens lockup, protects the rifling with a precision crown, and promotes smooth, consistent feeding with quality practice and defensive loads.

Why Choose a True Precision Barrel for Your G43

• 416R Stainless Accuracy: Premium barrel steel chosen for uniform microstructure and heat stability—helps produce tighter, more repeatable groups.

• Black, Duty-Ready Finish: Low-sheen protective coating over stainless fights corrosion and abrasion for EDC in any climate.

• Drop-In Fitment: Dimensioned for the Glock 43 slide—most pistols require no gunsmithing.*

• Enhanced Lockup Geometry: Carefully controlled hood and lug tolerances promote a consistent lockup and more stable point of impact.

• Optimized Chamber & Ramp: Designed for smooth cycling with SAAMI-spec 9mm ammo (FMJ and many JHP profiles).**

• Precision Target Crown: Protects the muzzle and supports long-term accuracy.

*Tolerances vary; always conduct thorough safety and function checks after installation.
**Always prove 100% reliability with your chosen carry ammunition before EDC.
