Helpful Positive Review Awesome Fit and upgrade. by Jon Steppe, Verified Owner, July 26, 2020
Looks cool and is a nice upgrade from the standard barrel. The barrel works well and I have not had any issues in the operation of my P320. Appears well made and the finish is a nice look that matches the OEM Sig p320 slide color.

Precision Engineering for the SIG Sauer P320 Compact Platform

Match-Grade. Suppressor-Ready. Performance-Tuned.

Upgrade your SIG Sauer P320 Compact with a TRYBE Defense Match Grade Threaded Barrel engineered for exceptional accuracy, mechanical precision, and enhanced versatility. Precision-machined from 416R stainless steel — a premium gun barrel material known for its high tensile strength and thermal stability — this drop-in upgrade delivers measurable improvements in shot-to-shot consistency, lockup integrity, and barrel-to-slide interface fit.

Whether you're building out a tactical setup, competing at the range, or simply refining your everyday carry pistol, this barrel is built to deliver outstanding results with both standard factory and match-grade 9mm ammunition. The 1/2x28 threaded muzzle allows for easy integration with suppressors and muzzle devices that enhance recoil control and sound mitigation. Each barrel comes standard with a precision-machined thread protector to shield the threads when a device is not installed — maintaining a clean profile for daily carry or range use.

Engineered with a 1:10 twist rate and precision-cut 6-groove rifling, this barrel supports a broad range of bullet weights and defensive hollow points. Every barrel undergoes post-machining stress relief and heat treatment, ensuring long-term dimensional stability and resistance to barrel whip, throat erosion, and high-round-count fatigue.

The drop-in TRYBE Defense SIG Sauer P320 Compact Match Grade Threaded Pistol Barrel requires no gunsmithing and offers match-grade performance and rugged dependability in a proven compact platform.
