I would like to get familiar with snap caps for my XD9. Anyone have any recommendations on which ones are good and reliable? Also, would I be able to dry fire with them? A lot of stuff I found online were about 50/50 on yes and no's. I am a new owner of an XD9 so I would appreciate the help. Thanks in advance fellas. Also, I'd like to know some tips from my fellow XD9 owners.
