This is the ProMag Smith & Wesson M&P Shield EZ 9mm 12-round magazine. 

If you’re looking to maximize the capacity of your M&P Shield EZ while maintaining a concealable footprint, this magazine may just be your best bet! 

With durability in mind, ProMag constructed these magazines from heat-treated steel and included an impact-resistant polymer base plate. Inside the rugged body is a chrome silicone wire and anti-tilt polymer follower, which also provide superior reliability.  

The icing on the cake? ProMag makes these right here in the United States! Whether you want more protection while carrying or reduce your time reloading at the range, you’ve found your magazine. 

We don’t know how long these will stay in stock, so you might as well grab a few before you check out!
