I have a Fox A Grade with a Miller SST. I'm not a huge fan of single triggers, preferring DT except on late season pheasant hunts when it can be difficult to wear a glove heavy enough to both keep your trigger hand warm and operate a DT. My Miller had a slight hitch in it when I bought the gun. Gunsmith friend corrected it. (He wishes to remain nameless so as not to become known as a Miller trigger mechanic.) I've shot it a lot since then, without a hitch. It's one SST that you can select when the bird takes wing once you get used to it.
