My wife isn't interested in my guns. She knows how to shoot, and I have dedicated a gun for her use in home defense. When I start talking manufacturers and model numbers, she asks, "Which one is that?" The only gun she doesn't have a good handle on is the Nagant 1895 7.62x28R revolver, complete with holster, that I bought using incentive gift cards from work. She knows my carry guns, sans nomeclature, my Remington 870 12 gauge, and the Ruger Mini 14 she bought for me.
So, I don't have to hide anything.
