Rob,

Did you ever get your CZ550 follower modified so that you can fit 3 cartridges down in the 585? If so, would you be willing to describe how you did it?

In particular, I am wondering whether a slightly wider magazine box is necessary, or if reducing the height of the follower was all that was needed.

Yes Rob I would like a description of that as well as I have specified to the smith that my mate and I both want 3 in the box for our .585's

Does the 602 differ in this respect??
