+1 Magazine Extension for Smith & Wesson M&P 9 Shield and 40 Shield Pistols

M&P 9 Shield and 40 Shield +1 Magazine Extension

You've asked and now we're answering. Introducing our newest +1 magazine extension for the Shield 7 round factory magazines. Made from carbon fiber reinforced nylon, this economical mag extension is no slouch in the engineering department, with the material being one and half times stronger than aluminum. Not only does the extension add an extra round making the mag a 8 round capacity, it also makes a nice space for your pinky to rest for a better grip. Get yours today!

Installation: Remove the factory base pad and floor plate from the mag tube. Our extension includes a cap on the front top and cap head screw on the bottom front for retention. Remove the cap head screw and cap to allow clearance for the mag tube and shoulders. Replace the floor plate under the mag spring with our new floor plate. While holding the new floor plate and spring up in the mag tube, slide the extension from the front of the extension on the rear of the mag tube to install the extension. Replace the cap on the front top of the extension and then turn the cap head screw clockwise from underneath until the cap is secure (no need to over-tighten, just snug it up). This will block the mag tube to keep the extension from sliding backward. Use a 3/32 allen wrench to make the adjustments.

Magazine not included.
