140mm Mag Extension for CZ Tactical Sport 9/40


Springer Precision 140mm extended capacity basepads for CZ Tactical Sport 9/40 are CNC machined from aluminum and hard anodized for a long service life. This lengthens the magazine and adds rounds to your magazine. The unique locking mechanism allows a very solid attachment with a simple backing out of the discrete set screw. They fit the USPSA 140mm magazine gauge. The unique attachment design provides a low profile, sleek design that is very stable and easy to remove. Compatible with the Czechmate.


Custom engraved and custom colors are non-returnable.

*We include a .050 hex driver that makes installation and removal a breeze.  

*Not recommended for use with the 26rd factory mags.  You will not be at the correct length (140/170mm) and even the normal extra power springs will probably not be strong enough.

**Disclaimer: As with all competition geared changes, always make sure you test and check your gear before you take it to a competition setting.  With 140mm/170mm magazine configurations especially, check the magazine in a USPSA 140mm/170mm gauge to make sure it fits.  With mass produced items like magazines, sometimes they can vary slightly from one to the next, often in the magazine lips that connect with the magazine extension/basepad.

Due to design variations, Springer Precision cannot guarantee compatibility with any other manufacturer’s aftermarket magwell, unless otherwise specified. Please email us with any questions.
