I agree that the longer and heavier a gun is, the more difficult it is to maneuver. On the other hand, if something like the Mossberg 590 series is such a poor choice of weaponry, why does every police department and military special forces unit* in this country outfit their personnel with the 590? They do so because they know that when TSHTF, it is the cheapest, most effective tool to maximize the probability that their boys aren't the ones who go home in body bags.
