Gauge is not a problem for either of us. The wife can shoot a 12 with no problem at all. It's the total weight of the shotgun itself she has trouble holding up long enough. As far as a Remington, I love them but I went back to a Mossberg because I am left handed and the Moss has the top tang safety which is great for either one of us. I think the 12 gauge coach gun with 20" barrels and exposed hammers will solve the problem of weight as well as the left-right handed safety issue. With only two shells in the shotgun, we do not have all the added weight of the extra rounds. I know I can down load to only two or three shells in the Moss, but that does not eliminate the additional weight of the tube, heavy wall barrel and internals of a pump. This is why I say it's very confusing to me right now especially after just buying the Moss a couple months ago and only shooting it less then a couple dozen times.
Wife wants something she can clear out the snake problem we have along with the pesky squirrels and coons that like the chew on wires around here.
I will hang on to the Moss until maybe I can come up to a nice fair trade that will make everyone happy.
