You stated that you are a proficient shooter with your G22, so I would guess that your wife does not have a problem with you owning a gun? Do you carry a gun in the private security business? Just thinking out loud. Do you carry at home? Is she otherwise ok with you having a gun? Are you a hot-headed individual and she fears you might pull your gun for the wrong reasons? What does she think is the difference between you owning and shooting guns as opposed to CC? Again, just thinking out loud. I would probably go with the advice to slowly keep feeding her news stories of robbery, rape, muggings, murder in the streets, etc. Have her attend a CCW class with you, like a date night. I guess I have it pretty lucky. My wife could care less if I carry concealed. She could care less about guns altogether. But she knows that owning guns is an American right, and carrying concealed is just an extension of that right. Good luck, I hope she sees the light.
