Admittedly, I didn't read the whole thread, and this may be in here - so I apologize if it is! Check out some of the John Conner Gun Crank Diaries, and look for his wife - The Memsaab Helena, and "Little Lizzie" stories. Very moving!
I've had this debate with my wife (who is not an anti either).
You're licensed to carry. The same reasons that she thinks it's good to have a weapon for protection in the home or car apply to you carrying on the street, only more so!
I can think of a lot of reasons to carry. I can't think of any legitimate reason for a responsible, law abiding, legally licensed, and qualified person NOT to carry.
One of my wife's reasons for not wanting me to carry was something along the lines of "what will people think?" The answer is that if they know, I've been too obvious! The bystander should NEVER know. That's why it's called concealed carry.
You'll probably never need to draw your weapon - most police never draw their weapon - but, when you do need to draw and defend yourself, your wife, your children, other innocents - you REALLY need to do so!
I don't klnow your status or hers on training. If you're not well trained get some training - take her. Go to a Gabe Suarez seminar, or if you can swing it, get her to go to a "Babes with Bullets" camp with Julie Goloski and Kay Clark Miculek (sp?). Good stuff!
Good luck!
