I know that it is important on my XD to rotate the magazines occasionally so the spring will work properly when it is needed. I am using a Remington 870 for HD purposes and I have been leaving 6 shells in the magazine. My question is if that is ok to do or should I just plan on loading it with shells off the shelf if it is needed. The problem I see with not leaving it loaded is that when it is needed it is not ready and in a situation you might need a shotgun you probably don't have those spare seconds. Any answers or thoughts? Comments?
