The manual says you can, but I created a divot above the chamber where the pin strikes on mine and had to send it back to Ruger for repair. If yours does this Ruger will fix it free of charge. But since I got mine back it hasn’t been nearly as reliable after they replaced the slide and barrel. I get frequent malfunctions now.I just returned from Academy with a brand new SR22. I am quite excited. This is actually for my wife, and the two of us are going to start plinking together.
The instruction manual gives safety suggestions while dry firing, and even says that the SR22 can be dry fired without damage to the firing pin or other components as long as the magazine is inserted.
However, from time to time I see comments from people that don't recommend dry firing a rimfire pistol. Is Ruger simply mistaken with what they say in their manual? I'm not trying to start something here, or stir up the pistol-police who hover these forums searching for opportunities to "right the wrongs".
