I have not been able to find one for the extended magazine however it is very easy to make one from a wooden dowel that you can get at your local hardware store you will just be making a longer version of the Mossberg plug Picture here https://www.mossberg.com/store/930-935-magazine-plug-dowel-16818.html
William, yes Sir. Listed here : https://www.mossberg.com/store/930-935-magazine-plug-dowel-16818.html
James G that plug would only reduce the magazine by 2 rounds to a 5+1 capacity (Dowel is 6 inches long) you would need the same type dowel 15 inches long to reduce the capacity by 5 to get to the desired 2 + 1 capacity
