is it really the 6.1 95? when i looked it up, the 95s are around 345 grams. the team version is 303 grams. i think you got a bad batch of rackets. wilson doesnt keep their quality control in place.
It is normal. A version of it, available in Europe and likely Japan has a weight of 309grams unstrung. However, if you wanted the 332grams unstrung version, well it's the wrong frame. It's a legit one, but likely not the one you wanted.
