Peterson, depends on Wich M&P shield you have. I'm guessing you're referring to the M&P shield plus, if so then yes the 15 round magazines will fit no problem. If you're referring to the Smith & Wesson M&P9 Shield or M&P9 Shield 2.0 then no because those use single stack magazines and the 15 round magazines are double stack and will only fit the shield plus/equalizer. S&W has quite a few models of the M&P Wich makes it confusing. if you have the shield plus here's a link to a 15 round magazine that will fit................... budsgunshop.com/product_info.php/products_id/149952/mag+m%26p9+shield+plus+15rd+ext ................ Hope this helps and hopefully explained it well.

If you are referring to the M&P Sheild plus then your answer is yes.

Peterson, I assume you are talking about the Shield Plus. (since the original Shield & Shield 2.0 do not come with 10rd magazines). If so, the answer is yes. S&W makes 13 & 16 round magazines for the Shield Plus. If you do not have the Plus, the answer is no, as that would be a single stack magazine.

Hi Peterson, yes Sir you can. The 10rd and 15rd magazines are physically the same size with the 10rd mags just being internally blocked to hold 10rds. Cheers and stay safe!
