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!)

  2. Bang for your buck 4 Star Review

    Posted by on 22nd Sep 2018

    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.

  3. Extra Rounds 5 Star Review

    Posted by on 11th Jul 2018

    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.

  4. more is always better 5 Star Review

    Posted by on 6th Jul 2018

    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

  5. Excellent product 5 Star Review

    Posted by on 2nd Jul 2018

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

  6. Works great no issues 5 Star Review

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

  8. Great, simple enhancement for M&P Shield 5 Star Review

    Posted by 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.

  9. Great Product - 5 Star Review

    Posted by on 14th Jan 2018

    Ordered two - and both have performed flawlessly. Yes there is a slight gap at the base of the extension - who cares - if you are that concerned with aesthetics - maybe you should take up interior decorating. Pretty doesn't always equal functional - I think these look great, if you have larger hands, these feel solid and comfortable in the hand - having added extra lead to throw downrange, they are still easily concealable, and mesh well with the overall design.

  10. No issue 5 Star Review

    Fired 3000+ rounds with this magazine extension, no issue at all. Good product.

  11. Complete junk 1 Star Review

    Posted by on 25th Aug 2017

    Do not buy. I bought two of them for my shield 9 and the first one the plastic piece inside broke off before the set screw would snug up. And both of them leave a large gap between the emp and the bottom of the mag well of the gun. Both were installed on 7rd mags, when installed on 8rd the factory follower doesn't go all the way down to the emp. Emailed both wing tactical and spike and neither will respond

  12. Poor quality and fit. 2 Star Review

    Posted by on 15th Aug 2017

    Doesn't work with the factory extended magazine and while tightening one of the set screws on one of the three I purchased the plastic set screw stop broke off so the screw now has no backing to tighten up against. When installed on the short magazine and installed on the pistol there is a larger than normal gap between the magazine and the pistol grip.

  13. Mag extention 5 Star Review

    I love the extra grip for big hands. I've recommended this product to all my shooting friends!

  14. Functional, but not perfect 3 Star Review

    Posted by on 13th Aug 2017

    The Strike Industries M&P Mag extensions were Easy to install and functional. After loading and reloading about 400 rds, thru two mags one seven round OEM, and one 8rd OEM, both performed flawlessly. On the 8rd mag because of the tension, it left a fairly large gap between the grip and mag which made it look odd, but still very much functional. On the seven rd mag less of a gap, but still a noticeable one. I don't think it left room to pinch your hand, but I could see it happening when inserting the new magazine.

  15. Glad someone else making +2MAG but.. 3 Star Review

    Posted by on 8th Aug 2017

    As far as feel, it matches the shield perfect and looks good, easy to installed. the MAJOR problem is that with it. It doesnt match the factory spacer for the 8round. Which is the whole point of added more rounds. both radius of the spacer and the extension dont match and looks terrible. It also pushes ths spaced at a wierd angle that makes the magazine hard to load and unload. I hope SI will either make a spacer that will replaced the factory one or just move the height of their product .250 or so, that way you dont need the spacer.

  16. Shield magazine extension 3 Star Review

    Posted by on 7th Aug 2017

    Was excited to actually get my hands on this product but was a little disappointed with the fit. When inserted into the firearm, the magazine plate does not sit flush with the mag well. There is a significant gap between the two. And on top of that, it is an uneven gap, wider in the front that in the back. After searching other reviews online, apparently I'm not the only one with issues regarding improper fit. However, feeds rounds just fine and feels great in the hand, just looks bad.

  17. 9mm Shield +2 5 Star Review

    Posted by on 6th Aug 2017

    Finally got my hands on the Emp +2 and SI delivered as always. I've been happy with every SI product I've ever purchased. At first I didn't realize this was made for the 7 round mag so I installed it on the 8 round mag. Works perfect either way. It looks better on the 7 round mag since it was made for it, also locks in place better with the 7 round vs the 8. You'll have to hit the 8 pretty hard on the bottom to lock it in place. Also the 7 round mag will no longer drop freely but the 8 will. With all that said I love the product and plan on buying more. I haven't used it enough to say whether or not I trust it with my life but so far I have no reason to doubt it. This was my first time ordering from Wing Tactical but it won't be the last. My package shipped the same day it was ordered.
