Thanks for the info. Another question though. Wasn't the 20 ga a larger frame than the 28 ga? So this would be a set of 28 ga barrels made for a 20 ga receiver?
Thanks
Yep, they built the 28 on a smaller frame specifically for the 28 gauge. (I miss mine). So I would assume you are correct that the 28 was added to a 20 gauge frame.
