thingiverse

Updated 7/10/2018 - Added a rotated version for printing in a different direction. This basepad/baseplate replacement is designed specifically for factory CZ 75 18 round 9mm magazines. It's intended to increase magazine capacity by one additional round, bringing the total count to 19 rounds. You can also use these as a quick identification method by printing your basepads in unique colors. Note that this extension requires the Mec-Gar Optimum metal retaining plate, which is sold separately. Without the Mec-Gar metal floor plate, this magazine extension will not function properly. The extension is compatible with the stock spring and follower, the Mec-Gar spring and follower, Wolff magazine springs, or any combination of springs and followers. However, it's recommended to test other springs and followers before use, as their functionality has not been verified. Loading a magazine with more than 19 rounds may result in too much tension, negatively impacting the firearm's proper function. It's suggested to load magazines only up to 19 rounds for optimal reliability. Durability testing has not been conducted, but it's assumed that these basepads will not hold up as well as stock ones. To maximize useful lifetime, treat them gently and avoid dropping them on hard surfaces.
