If you’re the proud owner of a Smith and Wesson M&P Shield, chances are you’ve got a couple of upgrades you’d like to make to your factory pistol. One of the easiest upgrades to make that can make a huge impact for almost any operator is the addition of an M&P Shield mag extension. Whether you really need more rounds, you’d like the added weight an extension brings for faster mag drops, or the idea of a little extra length to wrap your fingers around draws you to an M&P Shield magazine extension, the Tyrant CNC M&P Shield Mag Extension is an excellent way to get the extended magazine you want.

Why Do I Need a M&P Shield Mag Extension?

There are a lot of reasons to add a magazine extension to your M&P Shield as an upgrade. Here are just a few questions you might want to ask yourself:

Do You Have Large Hands?

For guys with big paws handling the standard M&P Shield is doable, but not the most comfortable fit in the world. Adding a Shield extended magazine creates an M&P Shield grip extension giving you a more comfortable controlled grip.

Do You Want Faster Mag Change?

The shooter who wants faster, more efficient magazine changes will welcome the addition of an M&P Shield extended magazine. The extension creates a faster changeover time as the additional weight will help empty magazines eject and drop away faster and more cleanly than their lighter weight factory issue counterparts.

Do You Carry Concealed?

The Tyrant Designs extension creates an M&P Shield extended magazine with smooth chamfered edges, making it more comfortable to carry on your body than a weapon equipped with a sharp-cornered magazine extension or even a sidearm without an M&P Shield Grip Extension.

Tyrant Does it Better

There are other ways to create an extended magazine, but you’ll be hard-pressed to find an Mag extension for M&P Shield that installs faster or easier. It’s easier to install the Tyrant Designs M&P Shield Mag Extension than it is to remove the standard base plate from your magazine. You’ll need a tool to release the endplate from your magazine, but you need absolutely no additional tools to install the Tyrant Designs extension. Oh, did we mention it gives you the capacity for additional two rounds? Yeah, it does that too.
