Greetings everyone, this is my first post in this forum. I?ve read a lot of information for both my cz?s but never wrote before. Thank you all for sharing.
I?ll like to know if anyone has ever tryed to install a mag extension intended for CZ75B on a CZ100?s magazine.
Dimensions on both mag?s are exactly the same, except for the rails which hold the mag cap from side to side. The difference is only 1.2 milimeters being wider for the CZ100 mag, probably for being a plastic cap.
I?ll try to post a picture so you can see where the 13th round sits (which is the maximum capacity of the CZ100?s mag), being my only concern that there might not be room for the follower to go further and thus impossible to hold any more rounds. (note the distance between the red and the blue arrows).

I forgot to mention before that both guns are 9mm.
Please let me know what you think or what you have experienced. It would be owsome to have a +2 firepower increase in my CZ100.
Thanks.
