Magwell Extension for M1811 Grip Module Features

The Brouwer M1811 Magwell Extension is designed to enhance the already generous magwell of the M1811 Grip Module for the Sig P320.

The Magwell extends the margin of error when performing magazine changes by increasing the magwell opening diameter and providing a smooth transition for feeding.

Special consideration was made to ensure that the addition of the Magwell would maintain the same grip index and repeatability of the M1811.

In order to achieve this the external profile was designed to minimize impact and interference with the users grip.

The rear of the Magwell was designed to fit below the profile of the grip to reduce impact to the users palm swell. The front and sides of the Magwell were designed to offer a secondary index point that cradles the users hand at the bottom of the front strap.

Compatibility

The Magwell is designed to work with factory 17 round magazines, as well as high capacity magazines without modification.

Material and Finish:

The Magwell Extension is made from 7075-T6 aluminum and is currently offered in three different coatings: Hard Black Anodized, or Anodized with color matched Cerakote in either Coyote or Black.

Perfect fit

The for and finish with the Magwell was perfect. I have large palms and relatively short fingers, so when I grip a pistol the heel of my palm flexes into the Magwell really hard. Previous Magwells on other firearms actually flexed out of place and offset the screw holding them on. The Brouwer steel Magwell doesn’t budge. Period. Magazines are incredibly easy to drop and load without looking. It’s sturdy and makes the finished setup look pretty sweet!
