Strike Industries EMP for Shield



There’s good news for those of you who have seen the Strike Industries EMP Magazine Extension for the Glock 42 or 43 and wanted one for the S&W M&P 9 and .40 Shield. Strike Industries now brings the M&P Shield Extended Magazine option to the market for these S&W favorites too. Enjoy improved grip and greater magazine capacity without sacrificing the look or continuity or feel of your favorite sidearm when you add on the SI EMP.

Enhanced Ergonomics

The Strike Industries Enhanced Magazine Plate for the S&W M&P Shield extends the total grip length of your 9mm or .40 caliber S&W M&P Shield. Larger hands find a comfortable grip they’ve never had before. No more pinkies hanging off the grip in midair. With the SI M&P Shield Magazine Extension, you’ll have a full hand grip and more balanced control than ever before.

Expanded Magazine Capacity

The extended length of the SI Enhanced Magazine Plate will allow the 9mm shield to hold two additional rounds while the .40 gains one. The EMP is compatible with extended length and standard factory magazines. Installation is simple using the included locking plate and screw Strike provides, you can then turn your standard mag to an M&P Shield Extended Magazine.

Quality Craftsmanship, Flawless Look, and Performance

Strike Industries creates the extended grip surface of the M&P Shield Magazine Extension from an impact resistant polymer and then textures the outer surface to match the Shield’s grip pattern, providing the shooter with flawless continuity of grip. The EMP matches the original grip well, making it an unobtrusive addition to your handgun. Its size is just right to provide the extension you need without interfering with concealment no matter how you carry.

  • Great product

    Posted by Mark on 23rd Sep 2019

    Bought two of these for my 7rd 9mm mags, and they work great. They transform the Shield mags into what they should have been in the first place. The stock 7rd mags are short, and I can't get a comfortable grip. The stock 8rd mags are more comfortable, but the loose spacer is pathetic. Inserting a new mag is sometimes troublesome if the spacer isn't fully seated as low as possible. These mag extensions provide extended capacity, comfortable grip, and more consistent mag changes. The molding is well done and blends nicely with the Shield's polymer frame. During installation, I did have the same issue as others with the set screw punching thru the plastic backing. I was expecting there to be more tension, but then the screw popped thru. No big deal... I backed the screw out, applied some blue Loctite, and reinstalled the screw just far enough to secure the locking plate.
    Overall, great product that I wish I had found sooner.

    Easy install, great functionality and I actually prefer the shape over the factory extended mag

    I have a SWAT member friend who uses this in his M&P 9mm Shield for his EDC. What more can I say?

  • S&W shield mag extension

    Posted by Paul on 22nd Feb 2019

    Extension matches shield mags awesome. Slight gap but just like factory mags. Took a little getting used to since it makes the 7 round mag/grip a bit longer than the 8 round factory, obviously it has an extra round. Happy with it, I did order 2 one for the 8 round mag which does need some modification to sit properly still happy with the extra rounds though it makes my 8 round mag my backup mag due to concealment

    What the hell people - learn to read before you order a product. It VERY CLEARLY states: "Designed to fit flush only on 7 round 9mm or 6 round 40 cal. M&P Shield magazines." If you put them on 8 round factory magazines OF COURSE they will leave a big gap. Giving this product a low score because of your own ignorance is the absolute hight of stupidity!!!
    (BTW, When used as intended they rock!)

    It works nicely. Ran a bunch of rounds through it at the range the other day and it functioned flawlessly. I put it on my 7 round magazine. Definitely like having 9+1 on my hip now.

  • Extra Rounds

    I love this extension! It makes the gun more comfortable to hold and adds 2 more rounds to my gun. Fit has a little gap between the gun and magazine but so does the 8 round magazine from Smith & Wesson.
