It might be prudent to add here (because you stated that you and your wife are new to guns) that a gun should ALWAYS be treated as though it is loaded.
Ensure that the muzzle is pointed in a SAFE direction.
These are reminders for your use of "snap-caps" and dry-firing practice.
Not trying to lecture here, but a gentle reminder might be helpful.
If you search, there are many stories about folks shooting their belongings or, God forbid, a living being, because they became careless while "practicing".
Currently, there seem to be the "4 Rules Of Gun Safety", but here are the original "Ten Commandments Of Gun Safety":
Always keep the muzzle pointed in a safe direction.
Firearms should be unloaded when not actually in use.
Don't rely on your gun's safety.
Be sure of your target and what's beyond it.
Use proper ammunition.
If your gun fails to fire when the trigger is pulled, handle with care.
Always wear eye and ear protection when shooting.
Be sure the barrel is clear of obstructions before shooting.
Don't alter or modify your gun and have it serviced regularly.
Learn the mechanical and handling characteristics of the firearm you are using.
Here is a more complete format:

Good luck, and be safe.
