CZ Shadow 2 Magazine Extension — Works With Your Magwell
Adding capacity usually means giving up your magwell — but not with this one. This Henning +5/6 extension is built to fit CZ Shadow 2 and SP-01 magazines with a magwell installed, so you get more rounds and faster reloads at the same time. On a Mec-Gar CZ-75 pattern tube, it takes a factory 17-round magazine up to 21 rounds on the stock follower and spring, 23 with a Grams Engineering kit, or 24 with an MBX Ultra Max kit. Gauged to the USPSA 141.25mm limit and ready for Carry Optics and Limited, with numbering dots, a side cutout for a positive grab, and a reinforced wall that stops over-insertion.
Important: Magwell-Compatible Version
This version of the Henning +5/6 basepad is designed for CZ Shadow 2 pistols equipped with a magwell. Its design provides the necessary clearance for use with compatible factory and aftermarket magwells.

Magazine Spring & Follower Options
This Henning CZ Shadow 2 +5/6 Magwell-Compatible Magazine Extension is available with several spring and follower options depending on your intended setup. An extra power magazine spring is recommended when using this extended basepad.
Want to retain slide lock? Select the Henning Extra Power Magazine Spring and reuse your factory follower. This is the recommended setup for customers who want to retain last-round slide lock.
Important: The Grams, MBX, and CSRG competition spring and follower kits are designed to maximize usable magazine capacity and do not retain last-round slide lock.
- No Spring: Basepad only. This option does not include a replacement magazine spring. An extra power spring is recommended when using this extension.
- Henning Extra Power Spring: Uses your factory magazine follower (factory follower not included). This is the recommended option if you want to retain last-round slide lock. View Henning spring details & compatibility.
- Grams Engineering Spring & Follower Kit: Competition spring and follower setup designed to maximize usable magazine capacity. View Grams kit details & compatibility.

Fast shipping from our Texas warehouse, and as the competition CZ specialist, our team can help you dial in the exact follower, spring, and round count for your division.
