To my knowledge no US Military has tested or opted for the Beretta 1301. Still, certain units in the Marine Corps used the 1014 . The 590 and 870 are still widely used even in the Marine Corps. But just like the 1911 the 1014 is a hoss, but the 1301 is no slouch, even though my round count on the 1301 is limited to roughly 3 months ( with no failures regardless of what I feed it) and My 1014 days started in 1999 I wouldn’t mine either weapons for an offensive or defensive situation. I’m blessed to own both.
