How about dry firing? Is it counted towards the 10,000 rounds Service Life S&W technician told me? In other words, will dry firing (with or without snap caps) shorten the Service Life of my 642?
Thanks for your input.
If the striker is actually on the hammer itself you will not only reduce the life of the revolver but you can actually damage it if you don't have snap caps.
As for the rest. Yes , it will count as far as spring tension and general wear towards the firearm but it will be fine.
If your hammer is flat and strikes a firing pin internally then you don't require snap caps , but I'd say if ya gottem usem.
