  1. Mark H. (verified owner)

    Love it. Went together easily despite the iffy illustration assembly instructions. More importantly, even though I have only run 72 rounds through it ,the function was flawless. Grip feels good and still easy to conceal. Will run more rounds through before it becomes my carry spare even though I don’t expect there will be any issues. Well built as well.

      Thanks for the feedback. Happy you like it

  2. Caine Morgan

    Awsome !

  3. Caine Morgan

    Awsome ! Works great. Instructions online were to a Glock and the extensions different but if you know how to take a clip apart it isn’t too hard. Functions well shot over 100+ rounds threw it and no jams or anything ! Highly recommended if you want to add some extra bullets to your magazine.

  4. rsarrels

    Just received mine was a little late but said would give something extra for waiting good customer service will review what they send on line the magazine extension works great would recommend this company to anyone thanks !!! Very happy!!!Rob

  5. Mike (verified owner)

    This +4 extension fits perfectly and is super easy to assemble and isn’t too big. I highly recommend! 5/5

  6. Alan Caron (verified owner)

    I just installed MPS 12 and am only able to fit in 10 rounds. I will continue to try this for a while and see if it starts to work to a full 12 around capacity. On the original configuration of the magazine I was only able to fit in seven of the eight rounds they shouldn’t have. I will check to see if there’s a malfunction somewhere inside.
    Any suggestion that would be appreciated.

  7. Bobby (verified owner)

    Does it not fit the shield 2.0?? Fits on the clip but loose when i slide it in the gun just falls right out

  8. Byron Blair (verified owner)

    This video did not help with installing on my MP shield.. Glock in Smith and Weston is two different gun all videos it’s just coming up for Glock

  9. Daniel Maschi (verified owner)

    Great quality, It does work with MP9 Shield 2.0 but ONLY works on the 8 round magazine, it will NOT work with the 7 round magazine.

  10. Shawn (verified owner)

    Not bad well built , only could fit 10 rounds tho. Can I explain the proper way to install it?

  11. Daniel Garrett

    Good but I’m only getting 10rnds as well tried 4different mags.

  12. Greg (verified owner)

    I have the same issue only 10 fit.

  13. Monte (verified owner)

    Doesnt fit the Shield Pro because the magazine is double stacked.

  14. David

    This is advertised as a 4 round extension and then you have a disclaimer in red that says if you must have 4 extra rounds then don’t order this. Either it is a 4 round extension or it is a 3 round extension, which is it? If you are adding it onto a factory S&W mag then it should add 4 rounds unless the manufacturer is playing pinnochio specifications here. Not all that difficult to figure out, its either a 3 or 4 round extender, but should be advertised and sold as one or the other without a disclaimer attached to it, especially since it is going for $30.

  15. Jeffery Willett

    Contrary to some of the reviews here I found this actually does add four! (4!) rounds to your 8 round Smith & Wesson M&P Shield 9mm magazine. Ignore the disclaimer unless you have some weak ass thumbs

  16. Strong Thumbs lol

    The weak ass thumb comment was legendary lol. I’m ordering one this week. I will give A follow up.

  17. Will

    I dont understand why everyone is having problems with only getting 2-3 rounds in or the magazine falling out of the gun. I have had absolutely no issues with getting 4 rounds in the magazine so a total of 12. I have the S&W Shield M2.0 9mm and it’s runs flawlessly every single time! To anyone that has any problems it could be your just not installing it correctly, or your not using the factory 8 round magazine and also do not use the little extension that comes with the factory 8round mag after you install the fab defense mps-12. I would highly recommend this if you’re looking for some extra capacity in your firearm. I just cant say I would trust it yet for my EDC, even though i have ran 1000+ rounds thru the magazine without a single malfunction.

  18. Berry

    Absolutely is a +4 mag extension for the factory 8rd magazine (7rd mags will not work as clearly stated) I think most people complaining about only getting 10 rds installed the extension improperly (extension spring follower turned backwards lol) when properly installed, loading 12rds is no problem and the magazine seats and locks with no more noticeable pressure than factory 7 or 8rd magazines on a closed slide in my experience. If I don’t pick up a Shield plus I’ll definitely be getting another one of these extensions 👍

  19. Bob Pearson (verified owner)

    Works great on my Shield 2.0. You have to use your 8 round mag for the extention. Holds 12 rounds. Last to rounds are tough to load. but a mag loader makes it easier. Printed direction are poor, but the vidio shows how to install the extention.
