CZ Shadow 2 / SP-01 - +5/6 Basepad by Henning

Our extended base pads are legal for USPSA Limited and Open competitions. Attached to the factory magazines they extend the magazine to 141.25mm length (5.56"). Whether you want to be competitive or not, these pads will extend the capacity of your Tanfoglio/EAA Witness magazines. These base pads are best matched with Grams Follower and Spring Kit which additionally increases the capacity. In fact, we only run our magazines in a combination with our base pads and Grams spring kits. Due to the design of the follower the slide may or may not lock back on the last round. 

  • For 9 mm / 38 super you will increase from 17 rounds to 23 rounds (requires Grams Kit)
  • For 40 S&W you will increase from 15 rounds to 20 rounds (requires Grams Kit)
  • For 10 mm you will increase from 14 rounds to 20 rounds (requires Grams Kit)
  • For 45 ACP you will increase from 10 rounds to 12 rounds (no Grams Kit needed or recommended)

These base pads will fit Grand Power 40 / 45 large frame magazines

Basepad weights aprox 26 Grams (.9 ounces)

    Works with mag funnel

    Posted by Travis on Jan 18th 2021

    These are great basepads. the machining is flawless and easy to install. I finally received my CZ-parts mag funnel and was able to confirm that these basepads work without issue. I did get the Grams followers and have had no feed issues.

    23rnds with mecgar 17rnd mags

    Posted by Ace Prater on Sep 23rd 2020

    My first ext basepads so not much to compare to. seems quality machining. I got the option with mag springs as well. The stock mags from the SP-01 will fit one more round, but they wont fee as good, so mecgar mags GTG.

    High quality

    It was a bit more expensive with the springs but worth it. It was very nicely made. I have some others with cheap set screws. These have a spring catch.

    Fantastic basepads

    These are great for adding +4 9mm. Look good, quality is spot on. They also work perfect with the CZ factory nickle mags. Would buy again.

    Ordered 4 of these for my nickle CZ75 mags. Fit, finish, and quality is outstanding. Would recommend. Ben Stoeger Shop customer service is outstanding and helped answer some questions that needed answers.

    Works great

    This extension and the spring follower kit works great. Got 23 rounds in my S2 mags. They function perfectly. The slide will still lock back when empty. And the extension is east to remove with no tools.
