hello JR, This is my first post since my account was activated just today by eric. my concern is about snap caps which i bought recently for my G19. after reading a thread posted by a respected shooter and armorer about glocks official word of using snap caps when dry firing a glock to avoid striker breaks.as you can see on the photo the primer is brass looking and i've tried pushing it using a pen to check if it is spring supported, found out that it is ( primer returns to position after slightly pushing it ). now my question is, is it safe to use? i was a bit concern what if the thing will damage the striker of my G19. I am from the philippines so sending any damage internals for my glock will take time and i don't see parts being sold here.
