+3 Magazine Extension for Smith and Wesson Sigma & SD and SD 2.0 9mm Pistols

Sigma 9mm and SD and SD 2.0 9mm +3 Magazine Extension

You've asked and now we're answering. Introducing our newest +3 magazine extension for the Sigma and SD pistol series. Take your stock standard capacity 9mm mag and adds 3 rounds to it. Will NOT work with 10 round mags. 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. Reuse your original magazine spring, follower, and spring base plate for an easy install. Get yours today!

Includes a cap head screw and cap on the top front for retention. Remove the retaining screw and cap, slide the mag tube on to the extension while holding the spring pad and mag spring inside the mag tube, then reinstall the cap and snug it up using the cap head screw to the top of the extension body to keep the extension from sliding forward. There is no need to over-tighten the set screw. Use a 3/32nd allen wrench to make the adjustments.
