Hi Derrick and welcome. No Sir. You will need the S&W M&P 9 (Standard, not Shield) Magazines : The Shield plus is a different series of gun and does not use mags that are compatible with the standard M&P series. - Cheers, stay safe and enjoy!

They would not be compatible with the S&W carbines.

Hi Derrick, no sir, the magazine is too short to be fully inserted into the magwell. Stay safe & have a great day!
