The case head is starting to peel back on my A-Zooms. I have a picture here of the used A-Zoom on the left and a brand new A-Zoom on the right. You can see the white line of bare metal on the A-Zoom on the left - if you look closely you can also see that the circumferance of the case is wider where that metal band around the case is.
The case is starting to peel back and mushroom out and if I load the A-Zoom on the left it gets stuck in the chamber / can't cycle the slide.
This obviously doesn't happen with the Tiptons.
