The purpose of this thread is to see what everyone's view's are on the different schools of thought when it comes to wear on the magazine spring when leaving magazines loaded for self defense. On one side, there are those who state that leaving the magazine fully loaded all of the time, wears the spring out faster and the magazines should be empty and rotated from mag to mag. On the other side are those who state that the consistent loading and unloading of magazines will, overtime, wear the magazine spring worse then if you would just leave them always loaded, there for they should be kept loaded at all times. Then there's the middle of the road side, that state that you can keep the magazines always loaded, just keep two rounds out of the magazine (13 rounds in a 15 round magazine) to be easier on the spring. I personally keep one 15 round magazine loaded with 13 rounds, loaded at all times for my Beretta M9. So what do you think and what do you do?
