Light and small enough to be worn IWB, OWB, in a pants pocket, a vest or coat pocket, a belly band, a shoulder holster, an ankle holster, and so on and so on...
Large enough caliber for excellent defensive work, especially with good hollow points.
Small enough to make it difficult to take in close quarters, and sans slide, so it can be fired in contact with the target without out-of-battery concerns.
You can change the grips to change the way it conceals, the way it feels in your hand, the way it aims for you, and the way it looks, and any combination thereof.
Closed hammer design = less crud in the works, less maintenance, faster/smoother draw, and no chance of being accused of cocking a hammer.
Revolvers go bang every time. Not infallible, but as reliable as a machine can get.
There is no safety to fumble with, no decocker, no hammer you can touch - point and shoot are the only options under high stress.
For me, those factors plus routine training make this size revolver an excellent compromise (and all handguns are compromises). Whether those factors plus (or minus) the five round capacity make it a good fit for you, only you'll be able to decide. Lots of people feel five-for-sure is plenty in their hands. Maybe give one a try at a local range, compare it to a steel framed revolver and some others, and see what you think?
The good news is, you're not limited to one firearm per lifetime... the bad news is, j-frames are addictive.
