I would have recommended against the P238. I've been carrying handguns (legally) since 1992, and still don't like single action autos.

The revolver was a good choice. My wife and I both have (and carry) S&W 642 38+P routinely. In fact, my 642 is a constant companion.

As Sumo said - the 357 will most likely be too much for her. My wife struggles with the recoil of full +P 38's in her 14.8oz 642. I can only shoot a couple of cylinders, before my hand is hurting. The LCR weights around 13.5oz so I think it will be a non-starter in 357.

Regardless, it was a good choice. The simplicity and reliablity of a quality revolver is ideal for self-defense. My wife actually prefers her Glock 26 (9mm), because she can comfortably shoot it better than the Smith, but this is a personal preference.

Congrat's, and good thinking regarding the training. Just owning a firearm isn't nearly enough - proper training is critical!
