1) Mossberg 500/590. It's good enough for the military, it's good enough for me. You get the same performance as other service pumps at a price that's lower than Remington; PLUS it's easier to load than a Remington since the gate stays out of the way when not loading.
2) Browning Citori. From the most basic models to the higher end stuff, this gun has more options than most (if not all) other doubles out there, this is a gun that simply will not fail you in the field or blasting clays.
3) Browning Maxus. For much the same reason as the Citori is good, so is the Maxus, just replace the word "double" with "auto"; i mean, it's a Browning after all!
