I know this has been discussed before but I just find this to be ridiculous and have to vent anyways.
The RCMP ruling on this doesn't make any sense. Once 4 shots are done then you have to MANUALLY rotate to the next mag(tube) of 4 rounds. To me that is a mag limit restricted to 4 rounds. How is that any different then inserting a new 4 round mag hanging off of a stock mounted mag pouch on a standard mag fed semi auto shotgun? It is still a manual operation regardless of how you look at it.
