I decided on the Mossberg 590a1 as my home defense gun but I been reading some not so positive reviews about this shotgun. I like the fact it passed military testing but some people said that that testing means crap and I read that some people in the military even said these guns malfunction quite a bit. And I see that the NYPD pulled their 590s do to malfunctions as well. This kind of has me worried that I made the wrong choice. Is there anyone on this forum who was in the military and has had combat experience with this gun that can back up these claims? Is this going to be a dependable shotgun for home defense?
