Mine are in a locked closet that also contains the gun safe.
If I'm not carrying a fire arm, it's locked in that safe.
This is the ONLY closet I've ever had that my wife hasn't moved into. It's the smell of the gun oil and solvent. It's a wife repellant.
And I don't have to keep my clothes in there either. She doesn't like the way my clothes smell when they are around gun oil etc. So, I actually get about an eighth of the big closet in the master bedroom for my clothes.
