We made this one (with +10 engraved) for show. The retail version has plain sides.
Since the dawn of USPSA’s new Pistol Caliber Carbine division, MPX fans have been hitting us up for an extension that would push their mag capacity to the max.
That day has arrived! Our new +10 for the MPX 9mm carbine incorporates various TF design elements into something head and shoulders above the competition.
Most importantly, our extension is easily removed WITHOUT TOOLS. Our thumbscrew-and-gasket system lets you spin the locking screw on and off with your fingers, yet the gasket holds the screw in place against vibration. If you over-tighten it (accidentally, or because you like things TIGHT) you can turn the screw with a flat-bladed screwdriver (or similar).

We angled the floor of the basepad to stand the mag straight up on a table for easier loading, which accentuates the lines of the gun.
