S&W should be using these on the original 8 round & 7 round magazines that come with the gun. These grips feel better and take only a second to replace. Just empty the magazine, push in the center button with a knife or small screwdriver and slide the old end cover off. Make sure you keep pressure on the bottom with your other finger keeping the base plate down and the spring from popping out, and slide this new Top Shot Grip cover on. I used it on my 7 round magazine. Now it feels like I'm holding something with the 7 round mag in the pistol. For the price, I think I'll replace the one on the 8 round mag too. I read one review that said it fit loose. Not mine. Not at all. Fits like a factory installed part. The one on the factory 8 round magazine is the one that is loose. I like this one a whole lot more.
UPDATE May 27 2017: Just installed a 2nd one on the 8rd Magazine. Fits like a glove, and really makes a huge improvement over the original extender that comes on the magazine. The black gap filler that slides on and off of the 8 round magazine is loose, as you will know if you own this weapon, that comes with the original 8 round magazine. So if you'll take the Top Shot Pros extender and replace the original with it, then use a little bit of silicone adhesive on the black gap filler that comes on the 8 rd mag, press it against the mag extender, wipe off the excess, put the mag in the pistol, and let dry. When it's finished the 8 round magazine won't have a loose piece on it, and it looks and feels like one solid piece. So for $15.00 you can purchase two and upgrade your M&P very nicely. Hopefully you can see from the added pictures in the update.
