I've had a Mossberg 500 (seven shot magazine) for home defense for about 3 years. Being my only defense gun, the magazine has been fully loaded almost 100% of the time, and I wonder if I should worry about the spring losing strength.
I target shoot about twice a month, loading a few rounds at a time, and I've never had any feeding problems, even with the last round out of the magazine.
So, not being a gunsmith, but being fairly mechanically inclined, can I remove the magazine tube from the receiver to rotate springs? If so, how? The magazine tube seems to be threaded into the receiver, but I've been reluctant to force it.
