75B Mag Size Options?

[Kraaken]

Hi - what is the largest mag I can fit into a CZ 75B and any recommendations on 'brand' or type, if their is such a thing?

Thanks for schooling the newbies like me.

Cz makes a 26rn mag that works.

Pro magazine makes. 32 rounder. That may or may not work as well

I would recommend CZ Factory mags and Mec-Gar mags ONLY. 
The SPO1 mags with the two available mag extenders and the spring and follower kit available at the CZ Custom shop, allows 23rds and I think 25 or 26rds .

If you buy the (#1.) Mec-Gar "+2" base extender, and the (#2. spring and follower kit, the SPO1 mag will hold 22 9mm.  I have one that works very smoothly.

Pro-mags have been VERY  unreliable for my son's CZ and numerous other posters on this and other forums.
