Was looking for a larger grip for my MPX. I bought the Magpul MOE K2-Xl but the slot cut into did not seem wife enough to mount properly. Also I noticed the beavertail was shorter than OEM. Any suggestions for a larger grip which will fit properly?

Try the HK MR556 grips. They have a pretty big palm swell. They come in multiple different angles as well so if youre looking for a more straight up and down style like the MAgpul K2, they might fit the bill.
