We have sights (10240) that have always been advertised as for the Thunder 9/40 or the Thunder 380 (10242) but I do not know if they share compatibility with the Thunder Pro. I've been trying to contact Bersa about this with no luck. But if you're willing and have the OEM sights and digital calipers, you can contact me at support@meprolight.us and you/we can measure those OEM Thunder Pro sights and see if any of our current sight selection would be compatible.
Meprolight has a comparison of the Meprolight Night Sights for Bersa Thunder Pistols in the daylight versus low light. The link below will take you to their website.

This product is for model 10242 which is indeed, a front and rear dovetail.
It should fit. But keep in mind that Bersa may have variations in their manufacturing specifications so it is not guaranteed that it will fit your individual gun.
Most likely not.
Most likely not.
No, it will not.
Yes, they should.
These sights will not fit that handgun.
Meprolight shows these as front tenon sights as well.
