I shoot an M21 Trap quite a bit, mostly for fun, mostly doubles, but registered once in a while. For me it is comfortable and I could go all day with it. As some of the previous posters have noted, the width of the barrels are a bit of a liability until you get used to them. I found that on angles I had a tendency to use the leading edge of the barrels as a centerline, much as you would with a single barrel gun, but that put the shot charge behind the bird. Once I realized the problem, things got better. I would lie if I said great, but certainly better.
