Does anyone know the difference between the Berertta 391 urika at around 800 dollars compared to the Walmart 390 version for 490 dollars? Alot of my friends duck hunt with the walmart guns. I don't really like thier loading routines but they have not failed them as mine hasn't either. When you shoot your last shot, I notice you can't just put one in the chamber and hit the release button and be ready to fire. If the 390 is just as good, its definately a deal compared to the 1187
