Key Features and Benefits
- 416R Stainless Steel Construction: Made from premium 416R stainless steel, known for its excellent machinability and corrosion resistance, ensuring durability and consistent performance.

- Precision Machining: Each barrel is CNC-machined to exacting tolerances, guaranteeing proper headspacing and reliable feeding with various ammunition types.
- Compatibility: Designed specifically for SIG P320 Compact and Carry models in 9mm caliber, offering a drop-in installation for most users without requiring gunsmith modifications.
- Enhanced Accuracy: The tight bore dimensions and quality rifling contribute to improved shot consistency and grouping, making it ideal for both recreational and serious shooters.
Technical Specifications
This barrel features standard SIG P320 Compact/Carry dimensions with a threaded or unthreaded muzzle option (confirm based on product variant). The 416R stainless steel provides excellent strength-to-weight ratio, while the Melonite finish achieves a surface hardness of approximately 70 HRC, significantly extending barrel life. The rifling is typically 1:10 twist rate, optimized for stabilizing 9mm projectiles.
Installation and Maintenance
Installation is straightforward for most SIG P320 owners familiar with basic disassembly. Always ensure proper headspace checking when installing any aftermarket barrel.
