    I like the fit of this extension on the factory mag. Pretty easy to install. The back metal plate which holds the whole bottom part in does stick when releasing the mag. I added a little lubricant to it and it helped so you don’t have to grab the mag to remove it.

  • Wing tactical mag.extension for the m&p shield.d

    worked as it was supposed to, added 2 rounds. Easy to install. It did require some modification to the magazine. To the plastic slide that covers the magazine on the shield. It looks great. Just like it was made for it!

    This magazine extension is very reasonably priced, shipped quickly and requires almost no effort to install. Now my pinky finger won't slip off!

  • Great Deal

    Great deal. Worth the buy for sure!!!!

  • Good for price, ok overall

    Posted by Peter on 21st Apr 2020

    This is 4 stars for the price. The gap left and amount of length added is not the best other alternatives (more than double the price). Are better. But there is nothing better for this price point.

  • M&P shield mAG extension

    Posted by Bob on 7th Apr 2020

    It works great on the short mag but it’s a little bit tight on the eight round magazine also on the eight round magazine a little bit of filing on the back Ridge let it fit a little tighter. Right now it’s very hard to get the eight rounder into the mag well when there is a round in the chamber but I Would expect that to loosen up after a while. I’m just glad it works so good in the short mag. If I needed more I would buy them again

    I bought 2 of these for my 7rd shield mags. I installed them as soon as they came in. The look of them with me shield was amazing. The lines matched up, and the design was almost spot on to the shield. Now for the bad part which is the reason for my rating...these come with a little backing plate that holds it to the mag. Without that installed the mags worked flawless ejecting from the gun with no issues. As soon as the backing plate was installed, which is necessary to have, the mags would no longer eject from the gun. I would have to actually pull them out. This alone is the reason for my review.
