Storm Lake S&W M&P 9mm Conversion Stainless Steel Barrel
Save money on ammo! Convert your Smith & Wesson M&P .40 S&W or .357 SIG into a 9mm by simply switching barrels and using a M&P 9mm magazine. Machined from certified 416R stainless steel for superior strength, durability, and accuracy.
Barrels are match grade, hardened to 40-42 HRC and cut broach rifled to shoot jacketed or lead bullets. All barrels are chambered for full case support.
All M&P barrels are drop in and will only occasionally require modification to fit.
