Awesome! Thanks for the great info!
I’ll look into getting some snap caps for those firearms you mentioned. I think dry firing is good practice for testing trigger pull. Just didn’t want to hurt anything. Would a spent casing be sufficient in the place of the snap caps?
A spent case only works properly for a few dry firings because the repeated firing pin strikes deepen the impression into the primer until the pin is no longer supported. A snap cap with a spring loaded cushion in place of the primer is the best way.
