You are set up well for choices
What do you shoot the best?
I really like the VP 9, A lot.
Modern 9mm is nothing to sneeze at. And with higher capacities it definitely adds some more capability.
I found with the right pistol and red dot setup I never lose the Red Dot during recoil and it makes follow-up recovery and requiring the target very fast. As much as I like my 45 ACP and 40 caliber that aspect makes 9 mm definitely worth it, in my opinion.
