If I got the 21 I would get it with the original style frame which is an extra cost item from CSMC.
My thought is to have an all around gun that I can shoot clays with and hunt with. I shoot clays with my 6 1/4 lb 16 gauge quite a bit.
If I got the Fox it would either be a 12 or a 20. What is interesting about the 21 is I could get a 20 with a set of 16 gauge bbls. I would consider a slim beavertail on the 20 gauge bbls and use that for clays and high volume dove and use the 16 with a splinter for pheasant etc.
It is just a thought. I'm still not sure I'm going to go the new gun route vs. an old english gun. Either way it is looking to be just shy of 20K.
I know these three options are very different but I like all three types of guns for different reasons.
