Buttcap difference Wilson pro stock/retail

Hello,

I own a H19 and a PS97S. I noticed that the Buttcap on the racquet are very different. They seemed both like retail but I noticed the H19 fits my hand much better. I don't know how to describe it. It just fills my palm much more and allows me to hold the racquet better on the bezels. It feels like the PS97S's Buttcap is really narrow whereas the H19 is quite wide.

Anyone knows something about this? if possible I'd like to buy the better buttcap to insert it on the PS97S

I have a picture on my phone.

Thanks
Mickael
