I had a fitting with Chris Batha a couple of years ago and have a completed sheet with my stock measurements. The try gun Chris used was an AyA, which has a concave rib.

When you consider purchasing a SXS with a raised rib, such as the Winchester Model 21, do you need to adjust the measurements-say for drop@comb and heel to alter the at face measurement? If yes, does the amount of drop need to be increased?

And, if it does need to change, how do you calculate/guestimate the amount of change required?

Thank you.
