Smith & Wesson 14421 M&P M2.0 9mm Luger 5.60" Threaded Black Armornite Stainless Steel

The Smith & Wesson M&P M2.0 9mm threaded barrel is a genuine OEM replacement and upgrade component for shooters looking to customize their M&P M2.0 platform pistol. This 5.60-inch barrel features a threaded muzzle, making it ideal for shooters who want to run a suppressor or muzzle device on their duty, range, or defensive pistol. The Black Armornite stainless steel finish provides corrosion resistance and a professional appearance while standing up to the rigors of regular shooting and cleaning.

If you're running an M&P M2.0 9mm and want the flexibility of a threaded setup without buying a whole new gun, this barrel swap is a straightforward way to get there. Whether you're suppressed shooting at an indoor range, setting up for serious training, or just prefer the look and function of a threaded muzzle, this is genuine Smith & Wesson engineering built to their same standards.

Armornite is S&W's proprietary stainless steel finish—durable, corrosion-resistant, and designed to hold up through thousands of rounds. At 5.60 inches, this barrel maintains the full-size M&P M2.0 profile you're used to, so handling and ballistics stay consistent with the platform.
