Beretta sent me one to T&E about a year ago. I ran maybe 600 field loads through it.
At first, it choked a bit on light 2 3/4" loads. At the end, it cycled 7/8 oz, 1200 FPS loads nigh perfectly. Heavier loads, no probs.
Overall, a good shotgun.
Downside, the manual lacks directions for changing the shims. We figured it out, but it took a while.
