No...

The main part of what you said that stood out was "she doesn’t have training..."

If she doesn’t know how to use it, it'll be dangerous to her as well as others around her. Pretending the kids are not involved in this portion and your wife is the only person in the house, I can see this being a problem for several reasons...

1. If she doesn’t know how to use it (Load, reload, aim, shoot, handle, if she's scared of it, etc...) she may hurt her self or others nearby
2. She may feel empowered and challenge the perp rather than flee for safety. This would clearly put her life in danger...
3. She most likely would not be ready to deal with the consequences if she actually took someone’s life. If you build yourself up to know that protecting your life as well as your loved ones life, you’ll normally come out of any defense situation with a clear conscious. If she’s not ready for that or she's not trained to deal with that, having a gun available for her should be your last resort…
