K Frame Model 65
Look no further. The gun you want is either a 3" K frame round butt model 13 or 65. One is blued, the other is stainless. In my opinion, the 3" K frame is the most ideal SD handgun offered.
Also, while being able to chamber the .357 Magnum is desirable. You're probably better off using contemporary .38 SPL +P for defense. The round is more controllable and costs less.
