Questions & Answers
I installed this barrel in a p320 compact slide. It won't function. It won't even go on the frame. The contours appear to be a little off. Why? Expert Answer

Please contact us at TechSales@OpticsPlanet.com and provide any photos that you can so that we can look into this for you.

Does the Trybe barrel come with the LCI cut out for the Loaded Chamber Indicator? I didn't see it in the sample picture. Expert Answer

Quality Performance by Dino, March 20, 2024
I am trying my hand at customizing my Sig P320. I got a great Apex Tactical trigger a few weeks ago that works like a champ. I also picked up a slide from Grey Ghost Precision. Very smooth charge and very reliable so far. I've purchased AR parts in t...

Does not fit as advertised. by Matthew Weber, Verified Owner, May 29, 2021

TRYBE Barrels are OK by CP, Verified Owner, August 1, 2025
I have two TRYBE barrels, one threaded to shoot with a Suppressor, and this one. They are well made and look great in a P320 build. Quality of materials and finish appear to be excellent. However, I find that I need to work hard finding a reload rec...

TRYBE P320 Barrel by El, Verified Owner, January 8, 2025
Needed a non threaded barrel for my P320 compact. Couldn’t pass up the price on the barrel. Barrel fit nicely into the slide, but when I took the firearm to the range a couple days ago the slide would stick to the rear not cycling through the rounds.

Read the reviews. I wish I had. by Corey, Verified Owner, December 23, 2024
Much like other 1 and 2-star reviews, this will echo. The spec and tolerance of the Trybe Defense barrel for the Sig P320 are not even close. One can see it with the naked eye. The slide will close if you can get the take-down pin rotated closed but ...

TRYBE Sig Sauer Compact Barrel by El, Verified Owner, January 8, 2025

Precision Engineering for the SIG Sauer P320 Compact Platform

Match-Grade. Duty-Ready. Performance-Tuned.

Upgrade your SIG Sauer P320 Compact with a TRYBE Defense Match Grade Non-Threaded Barrel engineered for superior accuracy, mechanical precision, and clean, snag-free performance. 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.

Designed for shooters who demand precision without the need for a threaded muzzle, this non-threaded barrel maintains a clean, snag-free profile — ideal for duty, concealed carry, or range use. With no external threading, there's nothing to catch on gear, holsters, or clothing, making it a practical and streamlined upgrade for serious users.

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 with consistent performance. Every TRYBE 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 Non-Threaded Pistol Barrel requires no gunsmithing and offers match-grade performance and rugged dependability in a proven compact platform.
