I was having reliability issues with both my Mossberg 590A1 & my Mossberg 500C. They would work fine until 3-4 shots in then fail to load a round. The magazine spring was weak. I replaced both today & function fired them. They both are fully functional & reported back for HD duty. I used Wolffe extra power springs. Not a bad fix for $11 delivered for each spring.
