S&W M&P 40/357 mags extensions

[ormmach]

Hello, I'm new to this forum but need to find a supplier for my MP 40 . I 'm looking for a mag extension in +2 or whatever. I got some feedback from this forum on this issue and checked it out, The supplier only has them if you buy there magazines.
I'm looking for something that will work with the S&W OEM mags.
Any suggestions would be welcome.
Thank's,
ormmach
