I just got my 930 spx back from mossberg , they replaced the barrel and a few internal parts. I tested with 9 different loads of bird shot and low recoil 00 buck shot, 0 problems. My question now is if i can keep it fully loaded? do you think the spring will get weak ? I know i can leave my glock fully loaded for long time without a problem, but i don't know about mossberg , any thoughts?
