I know this is a very subjective question but i'm in the process of building up my "grab N go" shelf in my safe. Grab N go meaning mags that are loaded "at the ready" in case SHTF or whatever. What is a good number of mags per pistol/rifle that you guys suggest? Right now, i'm buying mags based on 4 per pistol. Rifles i'm looking at 15ish. They will sit on the top shelf of my safe in the even that I had to "grab N go." I live behind a major college and also have a T station coming to the end of my street in a year or two so I want to make sure that I am ready for anything. I don't want to have to run downstairs and load mags before I can go, hence the grab N go. Thoughts?
