My milspec model 590 Mossberg's mag spring will not hold its temper much past one year with 6 shells stored in the tube (leaving room for two more). When I replaced it after a little less than two years, it was 6 inches shorter than the new spring. Does the mag spring need to be replaced in most shotguns (that are used for home defense or LEO work and kept loaded) every year or more often? Are there better springs than OEM Mossberg that would have a much longer lifespan? Obviously, in the unlikely event that the shotgun was really needed for self defense, it would be a disaster if it failed to feed due to a weak mag spring. Opinions??
