I do like the idea of a concealable being so light and small that you can almost forget you are carrying it, but the trade off is often a little gun that will spank your hand something terrible at the range. That is why I like my Berretta Tomcat 3032 that followed home a few years ago. It has a flatter profile and a bit lighter than this 22LR, and its a no pain shooting experience. But this revolver would be a nice simple to operate gun for my wifes purse.
Just make sure your wife is the one that picks it out.
My wife surprised me a couple of weeks ago. She had always expressed comfort using a revolver because they are simple and easy to operate. I took her to one of the local Ruger dealers with full intention of purchasing an LCR in .38 SPL for her. We ended up walking out with an LC9!
