You can't go wrong with any of the recommended firearms here. Just remember the most important thing here is that it fits you, and you can shoot it well. Like others have mentioned try a few out before you buy. I use a Sig Sauer P220 while working at the range, but at home i use a S&W 686 loaded with golddot +p 38spcl.
The reason for the revolver at home is my gf does not shoot as much as i'd like her too and has trouble manipulating a semi-auto; last thing i want is jam that she cannot clear. I showed her how to use it and refresh her every so often, and it seems like she has it down.
now I'm not saying that a revolver NEVER jams/malfunctions, but it seems that a revolver is less prone to user error.
