I'm ambivalent of 9mm revolvers due to problems with binding cylinders due to the tapered 9mm case backing out and jamming against the recoil shield. Others have had no problem with their versions. If you have one that works fine, 9mm makes the most sense, but you'll likely make a safer call by going .38sp/.357mag.
I had the money till they made me pay
Then I had the sense to be on my way
I had to stay in the underground
I was in the house when the house burned down.
