I think more than 100 in 16 Ga. also. The 28 is probably more than the 16 and 12 combined with the launch edition 20 the most produced. Judging this by the general feed back from when these were being actively marketed and produced. As I looked last you could still get one made for you in some models/gauges.
I have a 16 Ga, it's a very good gun that I shoot often and well as compared to others I have, it fits! Mine has a stock more inline with Researcher's small gauge guns. No pad system perhaps?
