Good to go. Look at army rifles as an example. We dry fire the he'll out of our weapons.
I've never met anyone who broke a wpn or proved dryfiring caused harm.
"...it will wear out the firing pin..." Nonsense. Dry firing a centre fire rifle or handgun won't do anything to the fp. Dry firing is a very old training technique for, breathing, sight picture and trigger control.
If you can't access the snap caps, you could try like i did and use a mag full of fired and deprimed brass with a touch of silicone in the primer pocket. Works for thousands of snaps lol and you get to cycle the action too.
only guns you dont dry fire, are multibarrel shotguns where the firing pins dont have a return spring, and .22's that aren't designed to be dry fired. anything else is fine. if you want to be safe, buy some snapcaps, they have a rubber "primer" which slows the firing pin down and reduces shock.
