  1. Great magazine for the M&P Shield

    Posted by Mick Sambasile on Jan 6th 2020

    These extended capacity magazines are great; they are well made and are reliable and offer more grip surface in addition to holding 10 rounds. Not difficult to load ammo and good looking.

  2. Best option on the market

    Posted by Tyler Mask on Dec 2nd 2019

    Item works exactly as advertised, I originally forgot to remove the plastic piece against the spring after I slid the OEM base plate off, totally my mistake but it made it a +1 instead of a +2. Take it from me- these things (tartan tactical extension) are way easier to put on than to take off. But once I fixed my dummy issue, everything was golden. Solid build quality, not as “weighted” as I thought it would be which is no complaint, still conceals easily when I’m carrying, also looks great, I may consider putting grip tape on it because after all it is smooth metal. Over all 5 star product and I WILL be purchasing in the future and recommending their products to friends.

  3. Excellent product. Excellent service

    Posted by Terry Powell on Nov 4th 2019

    I have ordered and used the 9 m/m extensions on my Shield as well as my XDM. They function flawlessly. As usual the service was excellent. I have sent two Glock 48's for the Combat package and fully expect the same quality of service. I would especially like to thank Sam for all the patience and help. Definitely a 5 star business.

  4. Excellent Upgrade for the Shield

    Posted by Fred O on Oct 4th 2019

    I purchased the 9mm version of the Shield magazine with Basepad installed. I've shot about 250 rounds through it since I bought it and it runs flawlessly. The pad adds minimal size to the magazine and the extra two rounds are worth the trade off. Fit and finish is perfect. I wouldn't hesitate to purchase this magazine. Spring is stiff when new but no worse then the factory model. A dozen or so loads through it and it becomes much easier to load to capacity.

  5. Sexy

    Posted by Unknown on Oct 1st 2019

    It looks great, adds 2 rounds for 9mm, bigger grip now. What else could you ask for?

  6. M&P Shield 9mm 10 round complete magazine.

    Posted by warren lee brown on Jul 10th 2019

    Great product. Feels solid. Like the fit and finish of the base pad. Was a little hard to get 10 rounds in at first but that is understandable. A little texture on the front of the base pad might be nice for when it is in the pistol.

  7. M&P 10-rd extended magazine

    Posted by Ron on Apr 30th 2019

    This mag is excellent! It is made very well! It’s built very well and looks great!

  8. Sent me 2 different colors

    Posted by No China products on Apr 18th 2019

    They sent me the wrong color and on of the extensions is two different colors one of which isn’t even on they’re website. So at this time I’m very disappointed because mismatched colors is something I’d expect from China.

    TTI Rep: I am sorry that you received the wrong color. If you contact us we are more then happy to swap it out for the proper color. Sometimes we end up grabbing the wrong item and send it out by accident. We are always more then happy to assist and remedy the issue. LT

  9. Much better choice than OEM 8 round

    Posted by RKHarm24 on Apr 17th 2019

    I had been using the 8 round mag in my Shield 9mm. It also had a Pierce pinkie lip floorplate. This TT 10 round magazine & extension is just a hair longer and I gained 2 rounds. Balances well when loaded in pistol.

  10. Great product

    Posted by Randy H on Apr 9th 2019

    The extra weight makes for smooth changes. Nicely made and work perfect.
