Decrease the speed of your magazine reloads with a larger "Big Mouth" to funnel the magazine into your M&P. These magwells are made of top quality stainless steel. Each magwell includes an insert to allow you to use any size backstrap on your M&P.

No modifications needed to install on your M&P 98% of the time. Since the receivers are polymer and molded, sometimes the length of the receiver is slightly out of spec. When this occurs, the magwell will not fit properly against the receiver and stock magazines may not seat properly. When the receiver is out of spec and too long, it will not allow the magwell to seat high enough to allow the magazine to lock into place. To resolve this issue, you may need to do the following:

Remove the magwell

Use a medium to fine grit sandpaper, laying it on a flat surface

Holding the sandpaper with your left hand and the receiver with your right hand (visa versa if left handed), slide the receiver, holding it square on the sandpaper, about 3-4 times. If you are not removing any polymer, you may need to add more pressure when sliding

Reinstall the magwell and test your magazine seating

If the magazine doesn't seat but almost seats, you may need to repeat #3

Excellent for use in IPSC and Steel Shooting.

The Heavy Open M&P "Big Mouth" will not work with stock magazines. Magazine base pads or extensions such as TF 140MM and 170MM Mag Extensions, CARVER 140MM and 170MM plus TTI 140MM and 170MM mag extensions and Arredondo 140MM(May require some mod) must be used.

The magwell is shipped with a smooth silver finish.
