Smith & Wesson M&P Barrels

Combat Armory carries 4 barrels for the Smith & Wesson M&P line, priced from $25 to $49.99 depending on model and finish. Options include the M&P Shield 2.0 9mm barrel in threaded and non-threaded versions, along with the M&P Compact Classic 1.0 & 2.0 and 4.25" barrels finished in Naked Stainless Steel.

All four barrels are chambered in 9mm and machined to the factory M&P chamber and feed geometry for a drop-in fit with no additional gunsmithing required. The threaded Shield 2.0 barrel uses standard 1/2x28 threads for a compensator, thread protector or suppressor mount.

Smith & Wesson M&P Barrels questions

Do these barrels fit both the M&P Shield and full-size M&P?

The catalog covers Shield 2.0 barrels and separate Compact and 4.25" barrels for Classic 1.0/2.0 M&P models. Check the exact model and length listed before ordering, since they are not interchangeable between platforms.

What thread pitch does the threaded Shield barrel use?

It uses standard 1/2x28 threads, the same pitch as most 9mm handgun thread protectors and compensators sold for comparable pistols on the market today.

Can I return an M&P barrel if it doesn't fit?

Unused, uninstalled barrels can be returned within 30 days of delivery. Barrels that have been fitted, installed or fired are not eligible for return under the standard policy.
