+3 Magazine Extension Magwell Version for SAR USA SAR9 Full Size Pistols

SAR USA SAR9 Magwell Version +3 Magazine Extension

You've asked and now we're answering. Introducing our Magwell version +3 Magazine Extension for the SAR9 pistol series. For those that have installed a Magwell to their SAR9 or have the SAR9 SOCOM Full Size. 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. The extension adds three rounds making the pistol a 20+1 now. Get yours today!

Includes a cap head screw at the rear for retention. Remove the cap head screw from the top, install the extension, then replace the cap head screw turning it clockwise until flush to keep the extension from sliding forward on the mag tube. Use a 3/32 allen wrench to make the adjustments.

Magazine not included.

Includes a new locking plate for those mags that come from the factory with a rectangular hole for the locking plate.

Listing is for 1 +3 Round Magazine Extension.

Fits SAR USA SAR9 Full Size with Magwell and SAR9 SOCOM Full Size Factory Magazines.

As always, proudly made right here in the USA.

*** A 20% restocking fee will be applied on returned magazine extensions that have been installed. Non-installed parts will receive a full refund (minus shipping). ***

Order 2 of the mag extensions for my Sar9 which had slight fitment issues. Contacted customer service with the fastest response from any company ever. They asked me what the issue was, my feedback and totally fixed my concerns and rectified everything. Most pleasurable experience. I will definitely recommend and continue to do business with them.
