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

This barrel is not a caliber conversion barrel, and will not fit the M&P 45 M2.0 4" 9mm pistol.

by TRYBE, Verified Owner, September 12, 2025
Can this be used to convert a M&P 2.0 Compact 4" barrel to 9mm?

It cannot, as this is not a conversion barrel. It is a drop-in replacement for a 4" 9mm M&P handgun.

Trybe M&p 4” barrel by Chillnsurf, November 16, 2022
It was Super easy to install and it was a great price for a spare/backup barrel. Now time to get some rounds down it and break it in! I’m Hoping to get decent accuracy from it but mainly just bought it for use on my little range.

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.
