CZ P-10 & Dan Wesson DWX +3 Magazine Extension by Henning
Add rounds to your CZ P-10 or Dan Wesson DWX without giving up reliability. Because the DWX runs CZ P-10 full-size magazines, this Henning +3 extension serves both platforms from one part. A spring-loaded plunger makes it tool-free to install and remove, it's CNC-machined and gauged to the USPSA 141.25mm limit, and it's legal for Carry Optics, Limited Optics, Limited, and Open.

Magazine Spring & Follower Options
This Henning CZ P-10 / Dan Wesson DWX +3 Magazine Extension can be used with the factory magazine spring and follower or paired with an optional competition spring and follower kit for increased capacity.
Want to retain slide lock? Henning has confirmed that the factory magazine spring and follower function properly with this basepad. If retaining last-round slide lock is important, reuse your factory spring and follower.
Important: The 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. Reuse your factory magazine spring and follower. Henning has confirmed that the factory spring and follower function properly with this extension and retain last-round slide lock.
- MBX Ultra Max Spring & Follower: Competition spring and follower setup designed to maximize usable magazine capacity. View MBX Ultra Max details & compatibility.
- CSRG Gen 2 Competition Spring & Follower Kit: Competition spring and follower setup designed to maximize usable magazine capacity. View CSRG Gen 2 details & compatibility.
Before selecting a competition kit: Review the linked product page for specific magazine compatibility, capacity information, installation, and other product-specific details.
Want maximum capacity? Add an MBX Ultra Max follower and spring to reach 24+1 on a full-size magazine — the same configuration as our ready-to-run CZ P-10 & DWX 24 Round Magazine Kit. Note: MBX and CSRG aftermarket followers do not lock the slide back on empty.
Tip: the P-10 and P-10 C have a short feed ramp, so run round-nose bullets for the most reliable feeding.
Ben Stoeger Pro Shop stocks this extension alongside factory CZ P-10 magazines and the CZ pistols and Dan Wesson DWX pistols these mags run in. Fast shipping from our Texas warehouse, and our team runs these guns in competition — just ask if you need help speccing it out.
