The Taran Tactical Innovations Sig Sauer MPX Base Pad Extension Kit gives you an extra 11 rounds of 9mm ammunition on tap for those long PCC stages. Like all of the TTI magazine extensions, it features their patented push pin design that allows for toolless assembly and disassembly for quickly cleaning or fixing malfunctions between stages. The single piece CNC machined aluminum design adds 4.7 ounces to help empty mags drop freely for faster magazine changes and won’t break on impact with the ground. This model features a black hardcoat anodized finish that will last. Included with the MPX magazine extension is a high power follower spring to reliably feed and activate the bolt hold open when the mag eventually runs dry.

Note: Remove the stock MPX base plate and floor plate from the magazine so that only the spring and follower should be left. Slide the base pad onto the magazine and then finish pressing it into place abruptly and firmly. Easing the base pad onto the magazine may result in the spring not dropping fully into the pocket in the base pad.
