I don't have any experience with the Vinci; however I own several other model Benellis. I was intrigued by the A400 when first released, and I purchased one shortly after. It was beautifully fit and finished, well-balanced, light, shouldered like a dream, and a natural pointer. And then...., I shot it. The recoil is (was) ridiculous, and that was with the patented "kick-off" system. Several friends of mine (all experienced shotgunners) had the same impression. I promptly sold it at a significant loss. IMHO, you should try the Benelli before buying any other brand. Just my .02$. GOOD LUCK.
