Hi. I have a MP45 M2.0 9mm 4". The non - thread barrel that you sale, fit in my gun ? Thanks

Can this be used to convert a M&P 2.0 Compact 4" barrel to 9mm?

Precision Engineering for the Smith & Wesson M&P 9mm M2.0 Platform

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

Upgrade your Smith & Wesson M&P 9mm 4in M2.0 with a TRYBE Defense Match Grade Non-Threaded Barrel — purpose-built for enhanced accuracy, durability, and versatility. Precision-machined from 416R stainless steel — a premium gun barrel material renowned for its high tensile strength and thermal stability — this drop-in barrel upgrade delivers tight lockup, consistent shot placement, and reliable cycling under all conditions.

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 6-groove rifling, this barrel ensures consistent accuracy across a broad spectrum of 9mm bullet weights — from standard FMJ to premium defensive loads. Each barrel undergoes post-machining stress relief and heat treatment to resist fatigue, maintain dimensional integrity, and provide long-term accuracy even under high round counts.

The drop-in TRYBE Defense Smith & Wesson M&P 9mm 4in M2.0 Match Grade Non-Threaded Pistol Barrel requires no gunsmithing and offers match-grade performance and rugged dependability in a micro-compact platform — delivering precision where it matters most.
