What about pulling on the triggers with the gun open, and then closing the gun with the triggers still depressed? That should let the firing pins down slowly . . . ?
This can be done on some guns but not all. "IF" the top lever latches open it is not convenient to do this. Also I have been told it should not be done on some ejector guns. I do this on my Lefevers whether extractor or ejector & a couple of others I have with double underbolts on which the lever is not latched upon opening. I have been doing this for years with no ill results though I am not a truly high volume shooter.
In light of the statement that spring breakage is a result of total cycles, not being left compressed, I would suppose that my proportion of cycles incurred in letting down the hammers to actual shots fired would be higher than a high volume shooters. However my total cycles, even including these would still be drastically less than a dedicated target shooter's.
My rates would be once at the end of a day's hunting while theirs would be once at the end of a competition.
I am not a metallurgical engineer so simply do not if the speed of relaxation of the spring has an effect on the number of cycles or no, perhaps someone will answer that.
