that's what I thought but after I called them I found out nope, they have 3 different units that measure less then 10 grs but nothing that will inter changeI know they offer a pistol model, you might try giving them a call. They have always been helpful in the past when I needed custom dies for wildcats I was playing with.
If the housing is the same, it would make sense that the pistol measure parts could be retro fit.
