I've always tried to avoid dry firing rimfire guns, but the manual says to pull the trigger to decock this gun for disassembly. If it's OK to dry fire to decock, how much can this gun be dry fired without damage?
Ruger claims that, due to the robust construction and the design of their firearms, that they can be dry-fired without a problem.
I was raised with the belief that you were going straight to Hell if you dry-fired ANY firearm, and have stuck to that for over 50 years now. Next range outing, save a handful of .22LR empties and use them as snap caps.... it'll make you feel better.
