20/28 ga?

Is that possible? 20s and 28s were made on different frame sizes! Probably a mistake by the seller.

I guess I posted about this gun 2 years ago when it was first advertised by Robin Hollow. I might have to call them; I don't think a 20/28 ga combination is possible.

Maybe they used original PB O frame 28Ga. barrels to make this set up.????

I called and found the answer. The gun was bought in the white from CSMC, and an extra set of barrels was made for it by them in 28 ga. to fit the 0 size 20 ga. frame ($$$:shock:).
