Hi all, I'm new to the site but not to guns. My question is......I have an m&p 40cal. I'm wondering if s&w sell a 357sig drop in barrel for it?? If so where can I get one??



Thanks Barry

A factory 357 sig barrel will drop in. I found one in the the classifieds for $40.

Check Brownells and Midway USA. You should be able to get a factory barrel there. You could also call S&W to see about if they have any.

Thanks, guys, I'll check the f/s section

Kahless, do you remember where you saw it?

You might want to check Storm Lake Barrels as well.

The .357 Sig barrels are no longer in production by S&W. Availability will be what was previously released. You might check Numrich/gunpartsinc.

Tr-enabling sells them. Do a web search for
s&w shield conversion barrels.
They cost $129.00 .

Thanks guys,I looked at both places and went with Remsport. Bought a barrel and some ar parts

I got one from midway, but that was months ago.

I got my Sig barrel from Storm Lake along with a 9 mm Conversion barrel so now my M&P 40 is triple caliber.

I was fortunate enough to get S&W factory barrels - a 357 Sig barrel and a 9mm barrel. Both work just fine. This of course was a couple years back when S&W sold them. Now I think you can only get 3rd party barrels but not sure.
