Simple and effective

This plugin is great! A simple but effective A-Z List for every post type incl Custom Post Types.
Important is adding the <? echo do_shortcode('[azindex]')> in a page template where you query your CPT. Create a new page and only assign your template. That’s it! No settings, no customization, just a simple php line. Because of the loop you decide what you want to see.

A big Thank you for Bob for his support!
