I work over seas and carry my XD-9 on a daily basis. We hit the range once a week for drills and fire any where from 200 to 400 rounds a week. Recently I had several feed problems. As I down loaded my mags to check them I noticed that the spring seemed weak. I took the mag apart and stretched the spring and that seemed to fix it. My mags are the croation stamped ones. Has anyone else had this problem?
