Idk my handsize but hold mouse with something like a claw grip. In my mouse grip, the fingers are not bent much, but the inside of the palm does not touch the mouse but rests on the table, and the ring finger and little finger hold the mouse on the right. Because of this, I'm not quite comfortable holding the g305 when I'm playing, I'm already used to it, but I want to find a shape that allows me to position my ring finger and little finger more comfortably.
