This may not appeal to average shooters, or even someone who wants a shotgun in his bedroom closet. I doubt most will want one for duck hunting either. The guys who will want one are the competition crowd and, the "tactical crowd". The biggest advantage to this, beyond faster reloads and increased capacity, is compactness. With a tube fed gun, the higher the capacity, the longer the tube. In 3-gun, a lot of shooters have tubes that project way past the end of the barrel, making them unwieldy and, prone to damage. I do think detachable box mags for semi autos will be coming shortly. I am a 3-gun shooter and a 590M may be on my short list for heavy metal division.
