Alright folks, a photos worth a thousand words.
Here's a photo series of an ACTUAL PINCH AND CHOP IN PROGRESS on Redux s/n 043.

CHOP! If a second ball sits above the the breech, this is the place and time it's going to chop, just as this one is.

The EXACT spot that the second ball pinches is the sharp "point" at the top of the milled section of the snub.

This is a second ball sitting comfortably OUTSIDE of the breech, resting on the snub. I had to manually "pull" this ball out for the photo.

The snub milling ahead of the feed port isn't aligned with the feed block on the slide.

A few points.
- The pinch doesn't happen because the first ball moves too far forward; it happens even with the first ball directly below the second.
- The ASP o-ring detent mod isn't going to work, not the way it would on the Phantom, because the problem isn't with the ball rolling forward, it's with the slide feedblock smashing the second ball into the snub.
- The last two photos above show a bolt I had milled. This leaves room at the bottom of the breech to install some kind of detent that would push the ball UP - quasi bore drop if you will
