Hey guys, I hear a lot of different opinions on this, but I'm trying to find a solution that works for me. How often should one switch out their carry magazine with fresh magazines in order to guarantee a long life for their magazine springs? At the moment I have three magazines that I carry with me daily (one in the gun, and two elsewhere). My goal is to purchase 3 more magazines and then begin rotating. The question is: how often to rotate? Also, is there a place to simply buy extra springs? I'm all about redundancy when it comes to having a gun that works long term, and I'm looking to get my spare parts inventory in order. Your comments appreciated.
