pedler, I thought you might like this. US Army Markmanship member Vincent Hancock won the International Shooting Sports Federation World Cup in Italy with a perfect 150 of 150 using an "out of the box Beretta DT10", 28" barrel 12ga.
If US Amry Marksmanship unit is using DT10s, or at least that is the choice of their primo shotgunner, there has to be some reasonable benefit and reliablity to this gun not reflected in the comments posted above. Of course I am sure he has a couple of them just in case of malfunction and Beretta customer service was probably prominently available at the World Cup in Italy so no poor reports would generate about their products at this level of visibility.
