When field stripping the XD 9 Mod. 2, you have to pull the trigger to release the slide. 1. Does dry firing the Mod. 2 harm the gun, firing pin, or striker pin in any way? 2. Is there any way to not dry fire? 3. Is there any way to use a snap cap so it is not dry fired? 4. Lastly, what is the purpose of dry firing anyway? It is not required on the XDM 9 MM 3.8 or the 5.25. I would like to hear what others have to say, and I would like to hear from Springfield. Thank you for your response.
