Will new model grip frames fit new model flattops

Maybe Im beating a dead horse, and am sorry but can you please inform of appriate fit for grip frames. Will xrsred grip frame fit on the new model bh flattops? I know the grip itself is a little different but does the rest match up closely? Im just trying to learn. I love single action rugers but only have a few years of playing with them behind me. I appreciate your generous assistance.
