I'm thinking Springfield XD. I'm pretty sure they make them with thumb safeties now if you want them or at least you'll be able to do so soon.
It won't have a hammer but it will have the capacity you are looking for.
Or you could try the Springfield EMP. It will have a hammer, but not your desired capacity. However, it would be out of your price range.
I'm going to vote for the Springfield XD.
