Spare barrel for M&P40

[Fasttalker]

I have a M&P40 that I am very happy with, but lately I have been thinking I would like the option of .357Sig. Who is producing and selling barrels for the M&P. I believe the only thing needed for the conversion is a barrel, but I may be wrong. Any help will be appreciated.

Smith and Wesson. Drop right in.

I used to like having this option with my Glock, good to know I can still do it

I have an M&P .40 and have a factory .357SIG barrel for it. If you want to pay more than the cost of a factory barrel then Storm Lake makes barrels for the M&P as well.

All you need is the barrel, everything else is the same. We have the Storm Lake 357 barrel in stock and can get the factory barrel if you'd prefer that one, Smith & Wesson® Performance Accessories from Speed Shooter Specialties.

I have a Full Size M&P 357Sig and I ordered a 40S&W barrel from "GunbarrelSupply.com". I know that "Midwayusa" also carries M&P barrels. I put my 40S&W barrel in this morning and went out and ran some Federal 165gr. HST through it, and they were as accurate as I could hope for.
