A single-action revolver may or may not be what you're interested in but the ruger new-model blackhawk is available as a convertable with a spare cylinder that can shoot 9mm. You would have even more versatility being able to shoot 3 different cartridges. Just food for thought.

Just got one in September in a 6.5" stainless, great versatile gun. Shoots really well. I plan to take a doe with it during the antlerless season with a heavy 180gr hunting load. It is proving accurate with both cylinders and a variety of bullet weights, I'm even getting a few found in 9mm, 38, and 357 that will shoot to the same point of impact at 20yds in the variety I've tested.
