Looking to convert one of my M and P 40's to 357 Sig. Is anyone besides KKM making barrels for this swap?

Also wondering about the new 10mm M and P? 9x25, 40, or a longer 10mm with a comp.? There must be someone catering to the SW crowd? I would love to sell off all my Glock converted guns! When I picked up a couple LE trade in's a few years ago, they instantly started going everywhere with me.

I tried to look over the forum but didn't see much or anything up to date about it.

Thanks if you can help.

KKM makes great barrels. Recommended to me by members here and a good college buddy. My first one made such a good impression on me I may be buying another one before long.

Another way might be searching for an M&P .357 SIG barrel. I see them on ebay now and then.

I don't know anything about conversion barrels for the 10MM M&Ps, let alone the required magazines for some of those calibers.

Good luck with it.
