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

Options:

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!

Includes a set screw on the rear side for retention. Remove the set screw to allow clearance for the mag tube shoulder, install the extension, then turn the set screw counter-clockwise until flush with the outside wall of the extension. This will block the mag tube shoulder to keep the extension from sliding forward. Use a .050 allen wrench to make the adjustments.

Magazine not included.

*** Need of an .050 Allen Wrench? Please select it from the drop-down before adding the Extension to the cart. If you are ordering more than 1 Extension and need only 1 Allen Wrench please add 1 with an ".050 Allen Wrench" to the cart and then click the "Continue shopping" button to return to the listing and select "No Allen Wrench" and add the additional quantity of Mag Extensions needed to the cart. Tools are non-refundable. ***

Fits Smith & Wesson M&P 9 Shield and 40 Shield 7 Round 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). ***

How about an extension for a .30 Super Carry Shield Plus? Would this work on that platform!?

Will the +1 round extension fit the factory S&W Shield .40 6-round magazine as well as the factory 7-round magazine? Thanks

We haven't tried it on that 40 round mag, the extension spacer the longer mag uses may not match up to the extension top since it is meant for the shorter mag.
