  1. Base pad for the S&W Shield 9mm

    Posted by Richard Hartman on Dec 25th 2020

    This was very easy to install and works flawlessly. I highly recommend this item to anyone who wants to convert the 8 round magazine into a 10 round magazine

  2. Base pad Extensions

    Posted by Combatmedicjcdsds on Dec 2nd 2020

    I bought 2 base pads and these are fantastic! Changed the grip for edc that I needed. I highly recommend them.

  3. Improves the grip on a small gun

    Posted by Jeff H. on Nov 12th 2020

    Easy install, and greatly improves the grip for larger hands. 10th round is a little hard to get in, but I'm sure it will loosen with time.

  4. Easy install, clean look

    Posted by Jason Z on Nov 11th 2020

    Easy to install and gave me two more rounds!

  5. Good Not Great

    Posted by Unknown on Oct 13th 2020

    It’s a little loose on the bottom of the mag. I have tried adjusting in as much as is possible it’s just not a perfect fit.

    Mag doesn’t quite feed the same, a little sticky on that first round of 10.

    Admin Response -

    Please email us at We would love to troubleshoot with you on the feeding issue. As for the gap, we have designed our M&P Shield Base Pads to not be a flush fit as overall that proved optimum functionality.

  6. Buy it

    Posted by Sean S on Oct 7th 2020

    It makes a huge difference! I've always disliked the 8 round magazine because of the little extension sleeve piece. With this base pad you get a full grip that feels solid and looks cool.

    It does increase printing...but not enough to keep me from carrying it.

    Mine is capable of holding all 10rnds with one in the pipe.

    If TTI made them, I would run this on all my pistols

  7. Great Update For My Shield

    Posted by Unknown on Sep 28th 2020

    Installation was very easy. It fits great in my hand and works amazing. I will definitely be back for more products.

  8. Huge Improvement on Shield Magazine

    Posted by Bill B on Sep 2nd 2020

    I've purchased a handful of products from TTI and I think this is definitely one of the most valuable. I absolutely hated the stock S&W Shield 8 round magazine with the sleeve that fit over the magazine. The TTI extension breathes life into your magazine. It looks amazing, adds a little weight to the bottom for ease of mag drop, and gives you additional capacity.

    My 1 negative of the extension is that for some reason I'm only able to fit 9 rounds into the magazine when a round is chambered. It can fit 10 rounds, however with the round in the chamber I can't fully seat the magazine. Regardless, it's more than I had before so I'm certainly happy with the TTI mag extension.

  9. +2 Mag

    Posted by Joe on Jul 27th 2020

    Received 2 extensions within a week. Install was easy and requires little knowledge. Couldn’t be happier with the whole process and the way it looks! My only complaint would be that the package came with 1 longer mag spring and no where did it tell me for which mag it went to (I ordered one for a glock and another for a m&p). But, the spring is not for this one, it’s for the glock. I will not buy any other extension!

  10. Good product

    Posted by Unknown on Jul 16th 2020

    Installs pretty easy and functions as expected no issues. Would buy again.
