+1 Magazine Extension for Walther PK380 Pistols

You've asked and now we're answering. Introducing our newest +1 magazine extension for the PK380 pistol. 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 9+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. Back the set screw out enough to clear the mag tube shoulder channel on the extension. Install the extension, then turn the set screw clockwise until it blocks the shoulder of the magazine body to keep the extension from sliding forward. There is no need to over-tighten the set screw, it is only used to block the mag tube from sliding backward and should be flush with the top of the extension. Use a .050 allen wrench to make the adjustments.

*** 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. ***

*** 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). ***

    Should work normally, lock back is driven off the follower which is not altered, just more space added to the bottom for an additional round on a stock walther mag.

    Love the extra capacity. Only gripes i have is that the plate is to be completely back or the follower wont go down and also the front doesnt come out far enough and doesnt have that pinky hold. Still giving it 5 stars because its nice to have 9+1 capacity
