Favorite single selective trigger - that's like asking me what's my favorite Michael Bolton song. (apologies to all the Bolton fans who hang out here....*g*) I once owned a gun with a combined safety/selector switch on the tang and hated it. For the admittedly rare times when you tried to quickly flip the safety and change barrels, it would sometimes hang up and the safety wouldn't disengage. I still own one gun with the selector on the trigger, and it's OK, but I think a double gun ought to have double triggers, period.
