Operating from memory here but two things to keep in mind should you get the cocking lever Too Loose.
First you may get firing pin drag from the hammers being delated in their start to cock.
Second, even worsr, as I recall upon the hammers reching full cock the cocking lever serves as the bbl check. If the bbls rotation is not stopped by the lever then the lower edge of the forend iron will strike the frame bottom. This puts tremendous stress upon the forend lug & could eventually lead to the solder joint being sheared. I have seen this on a hammer gun which did not have a check.
