Just came into an excellent fluted 629-2 with blued scope rings that fit on the slotted rib of the barrel. Can anyone recommend a tried and true and durable red dot "tube" for this model? Or, a holographic sight? I can afford reasonable products but not expend dollars for super high end. I'd like to purchase a durable sight less than $400. Thanks in advance for your opinion and time. [This one has 1" rings]. tkdguy
