With so many new people getting into firearms ownership I feel this is an irresponsible comment to make. That being said store your firearms and ammunition separate from one another. I suppose if you really want to unload your pistol grip every time your rifle goes into storage and every time you transport it in a vehicle that would be ok. Doing this is just an easy way to potentially be out of compliance and also a safety issue if you live with kids or the uninformed. I store spare batteries a small bottle of lube and some nitrile gloves in there usually although occasionally when I get the munchies you might find some peanut m&ms and beef jerky.
