Sounds to me like it's too smooth without the wall you mention. You'd rather feel that resistance at the end of the trigger stroke.
If I'm reading it right. I don't honestly know how that could be created. Mine are smooth throughout the pull so you can't really stage the trigger much. I find that I shoot better when I don't stage also. Just pull through like a DA revolver.
Let me know if I'm not getting the correct message.
