Sig P239 +1 Mag Extension

You've asked and now we're answering. Introducing our newest +1 magazine extension for the Sig Sauer P239 .357 SIG / .40 S&W or 9MM pistol series. 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 one round making the pistol and 8+1 now, it also makes a nice space for your pinky to rest for a better grip. Get yours today!

Includes a set screw on the top rear for retention. Tighten the set screw clockwise until flush with the extension shoulder to allow clearance for the mag tube shoulder, install the extension, then turn the set screw counter-clockwise a turn or two to block the mag tube shoulder to keep the extension from sliding forward. Use a .050 allen wrench to make the adjustments.
