It only fits the 30 super carry plus.

This fits the M&P 30 super carry only

Hi Mark, this does not fit the EZ model. The EZ uses a single stack magazine, this is a double stack mag.
There are no magazines more than 10rd for the EZ model.
Stay safe & have a great day!

No, the Smith & Wesson M&P Shield Plus .30 Super Carry 13-round magazine is not designed to fit the Shield EZ (or "Super Easy") models, as the Shield EZ and Shield Plus are different models with incompatible magazine systems.
Here's a more detailed explanation:
Different Models, Different Magazines: The M&P Shield Plus and the M&P Shield EZ are distinct models, and while both can be chambered in .30 Super Carry, they use different magazine systems.
Shield Plus and Shield EZ: The Shield Plus and Shield EZ are two different models, with the EZ having a slide that is designed to be easier to rack.
Mag Compatibility: The 9mm Shield Plus magazine will not store .30 Super Carry cartridges, and .30 Super Carry magazines can be loaded with 9mm but will likely have feeding issues.
No "Super Carry EZ Plus": There is no model called "Super Carry EZ Plus".
Shield Plus and Shield EZ are two different models: The Shield Plus and Shield EZ are two entirely different models.

Hi Mark and welcome. No Sir, the two handguns use totally different magazines. -- smith-wesson.com/product/s-w-magazine-shield-ez-30-sc-10-round ----------- Cheers and stay safe!
