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.

    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.

  • more is always better

    yes not best choice for 8 round mag .....great for 7 round mags . easy to install . if had included allen key would have been nice, but not mentioned in product description just had to get up and chase down the right size fussing the whole time lol.....but if you have large hands this is a must ! also have a black marker handy to blacken the gap-area if it bothers you ,you will understand when you see it not a big deal but just in case you have someone that notices every little detail

  • Excellent product

    2 more rounds on my MP Shield and it made the grips a lot more functional for my bigger hands.

  • Works great no issues

    Installed exactly/as easily as described. Feels great. Is an almost perfect match to my shield. Highly recommend.

  • Great, simple enhancement for M&P Shield

    Posted by Steve on 12th Mar 2018

    The EMP for M&P Shield 9mm is a very simple yet essential upgrade for the weapon. Though it may slightly increase the profile when (depending on how) carrying concealed, it still offers more capacity while maintaining the minimal size possible. The design and finish of the polymer is amazingly similar (almost identical) to the manufacturer's, giving the product a higher quality. The magazine sits just as flush with the EMP as it does with S&W's floor plate. Installation was easy, and the cost of the product is good too. I recommend this product.
