Kevin, unfortunately no, they do not use the same magazines. The EZ uses a single stack magazine, while the Shield Plus magazines are double stack.

I can tell you first-hand no as my wife owns a Sheild EZ. As mentioned, single stack mags for the EZ while the shield plus utilizes a double stack mag.

Kevin, no, as others have stated the ez uses thin single stack magazines and the Smith and Wesson shield plus uses wider double stack magazines. If interested here's a link to 15 round magazines that will fit the shield plus................. budsgunshop.com/product_info.php/products_id/149952/mag+m%26p9+shield+plus+15rd+ext ..................

Hope this helps.

Hi Kevin, no Sir. Currently the EZ Magazines are Single Stack and proprietary to the EZ Pistol. The Plus uses double stack magazines which are too wide for the EZ magwell. Cheers and stay safe!
