The shape of the Pro Wireless Gaming Mouse can be described as a variation of the Logitech G Pro X Superlight 2. From the degree to which the front and rear flare out, to the position of the hump, and to the general dimensions, the similarities are very apparent. The hump is slightly more tapered on the former, the top appears more rounded towards the sides, and the mouse ends up being marginally shorter, but other than that, these two mice are almost a match. While the main buttons are framed by ledges on either mouse, they are narrower and more elongated on the Pro Wireless Gaming Mouse, although the depth of the comfort grooves is virtually the same. In short, anyone who has ever used the Pro X Superlight will feel right at home with the Pro Wireless Gaming Mouse.
As for grip styles, I'd say the Pro Wireless Gaming Mouse mostly suits palm and claw grip. It is a medium-sized mouse with a moderately pronounced hump, which should make it generally suit most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the Pro Wireless Gaming Mouse very comfortable in claw grip.
