There have been suggestions made regarding shotguns. I don't know if any new laws have been adopted anywhere though. Among some of the suggested new laws are; Long guns with revolving cylinders which could include the Rossi circuit judge but it could also include something like the Xrail. Also magazines holding more than "x" number of shells so some extensions would fit that. Mossbergs JM Pro 930s and their goose gun 930 would be affected. Then of course there are the pistol grip and thumb hole stocks. I don't think any of those have happened anywhere though.
