I've always liked low profile mice and the waizowl cloud xs just does it for me. I was also using the model O 2 mini before.
Let me jot this down while my memory is still fresh. Context: I’ve been testing a few mice recommended for claw grip users with a palm size of around 18cm. From left to right: Lamzu Atlantis Mini Pro – Has a slight middle hump, ideal for those who prefer their mid-palm not touching the mouse. I eventually chose this one as its size and weight fit perfectly for what I was looking for. Glorious O2 Mini – Feels quite similar to the Lamzu Atlantis but has a more ambidextrous shape. Pulsar X2 Crazylight – Out of stock, so I can’t recall the exact feel, but I remember it having a less pronounced middle hump. Endgame XM2 WE – Slightly higher mid-hump, so the palm makes more contact. It’s also larger than the Lamzu Atlantis Mini Pro. Logitech Pro X Superlight 2C – The priciest of the bunch, but it has the best click feel—sturdy and responsive. Very comfortable grip for my palm size, though I skipped it since it’s over 200 SGD here. Glorious O2 – My current mouse, but it feels a bit too large, which is why I decided to look for a change.

Model o2 wireless Amazon used. Just got one best mouse ever
I got the used one on Amazon because it was $50. The wireless one is $69 right now. Check it out
You said he currently uses the Glorious Model O, look what it says underneath the mouse. If he has the regular Model O, go for the O 2, he will have a new mouse, that feels familiar. If he already uses the O 2, maybe go for something like a Zowie U2-DW, it looks similarly shaped to the Glorious but has a better sensor. Edit: Just saw there's a Model O3 already available, so you could get him that.
