The Big Mouth Magwell has the widest magwell opening compared to similar products on the market.  Available in silver or black-anodized aluminum, the Big Mouth Magwell fits STI or SV grips and flat or arched mainspring housings.  It offers a slip-on fit that requires no gunsmithing. 

The angles have been cut to provide the largest opening to reload to with the least weight (only 1 1/2 oz.) and size.  The magwell opening is 1.95 inches wide by 2.65 inches long, thus providing two-and-a-half times as much area as the stock opening. The sleek design not only accelerates your reloads but also supports the heel of your hand.  The flare at the back supports your shooting hand, pushing it higher on the gun during recoil.  This platform locks your hand into the same shooting position for each shot.
