This gun falls into the "laying across the knee" category. I should also mention that it is very difficult to reassemble: getting the barrels back on the frame is really a trick. It requires a fair amount of tricky pressure to keep the hook down over the hinge pin to compress the slide in the raceway that holds the barrels on (and activates the crossbolt). The lump with the hook wants to ride up and out of the frame. It is tricky enough that I'm never sure I'll be able to get it back together if I take the barrels off.
With the barrels off, the top lever is still very stiff. The thumb safety is also stiff. Ejectors work fine when dry fired with snap caps: some extra effort is required to open the gun to depress the ejector springs but not enough more to make me think that the ejector mechanism is a substantial part of the problem.
