Lightweight mouse feels heavy and uncomfortable

Hello, I have an Attack Shark X3 that I put grip tape on to make it easier to grip. However, despite the mouse being 49g, it feels heavy and uncomfortable to hold and control. I have tried to grip tighter to try to be able to control it better but my pinky just starts hurting. Is this mouse too big for me or am I gripping it wrong (I have tried all sorts of grip positions, but none have felt comfortable)? My hand size is 16.8cm x 8.8cm.
