I’m working on a CZ 75 pre-B and am having trouble with magazine fit. The magazines do not drop free and require considerable effort to extract. My goal is to get any CZ-compatible magazine to function properly, but Mec-Gar magazines are the most problematic.

So far, I have:

• Filed and sanded the inside of the grip on the trigger-side area
• Filed and sanded the rear of the magazine well
• Slightly straightened the magazine brake

These changes have made the magazines easier to remove, but they still do not drop free. I’ve attached photos showing the areas I worked on.
