What are the effects, positive or negative, from using a dry lubricant on a Crosman hammer/striker? Moly powder or tungsten disulfide? Would it help with SD or ES, or make things worse?

I have had good luck with moly powder. I burnish the hammer and the tube.

I think a dry lube is likely less problematic than an oil.... because the oil can pick up dust and get gritty easier.... Also, it can increase in viscosity in cold weather.... Having said that, I have never tried a dry lube....

My pumpers can dump a little more air when the hammer is dry lubed with MOS2 compared to being lightly oiled. The viscosity of the oil creates significant drag compared to moly powder. Just like the other poster said, it only needs to be burnished in. Less is more.
Tungsten disulfide (WS2) should be even better, but I have not had a chance to try it.

I have had good results with spray on moly - it is easy to apply a nice thin coat of moly on any part you want, and then it "self burnishes" as you use it. And there is no excess hanging around inside the gun, as I spray the parts outside the gun, and then install them after the carrier has flashed off.
I have used it on hammers and in the trigger groups of my guns and it has worked very well.
