Most Helpful Positive Review Very Well Made
Solid design and well made. Fits the magazines flawlessly and looks sharp when seated. I carry two extra mags in my pocket - which means I now have 6 additional rounds to fall back on in a crisis situation (God forbid). Could use a knurled texture for extra added grip - but works great as is.

Good, but not great!

by Bill, Verified Owner from KY, United States Written on November 7, 2021
I ordered two of these for my M&P 2.0 subcompact with 12 round magazines. One worked great, the other however not so much. The supplied allen wrench broke off in the set screw that TOO tight. Had to drill a hole on the other side of the extension and put a roll pin (spring pin) in it to secure the magazine. That was after using a hack saw on the original screw that wouldn't back out just to get the magazine to slide into the extension. After that it worked well.

M&p9c mag extension

by James, from WA, United States Written on May 2, 2021
Installation was quick and easy, and the fit and finish is great. Makes the gun feel perfect in my hand now. Being made of metal gives it a robust feel and doesn't feel like there is added weight throwing the balance off.

Junk - useless directions

by gjimmyj, Verified Owner from FL, United States Written on July 18, 2020
The directions are useless. Apparently, there is supposed to be 2 Allen wrenched provided-one larger than the other. Only one was included and it’s not worthy of being a toothpick. Part of the problem is my M&P 9c Cartridge has a very stiff spring and it bent the tiny Allen wrench. I had to use a jumbo paper clip to hold the spring in. Then, aligning the tab into the hole is a total Disaster. Don’t buy this for a 9c unless you have powerful fingers and unlimited patience.
Would recommend: No

Nice fit, well made

by CE, from MN, United States Written on January 19, 2020
I saw a review for this on YouTube and thought I would give it a try. The extra three rounds are very nice, does not add that much extra length. Very well-made overall, tight tolerances, fit very well. My only complaint is that it is smooth and will need a little grip tape to be ideal.
Pros:
  • Well made, tight tolerances
Cons:
  • Aluminum smooth
Would recommend: Yes
