Very nice, you'll get used to the recoil. Lean into it. Own it.
Although, they are a light gun so I believe that lends to it having quite a solid punch to it.
On my MP, I added a slip on pad because the stock one is just a tiny, thin, hard piece of rubber.
The pad on yours looks better, I haven't used or seen a TS stock in person to know for sure.
My recoil pad adds about an inch and half to the LOP, but it feels great because of the Hatsan's short stroke action.
It gives the shooter two places to grip the forend. I hold the forend in the grooves closest to the receiver. So comfortable. Very well balanced.
