While all the revolvers listed are excellent choices and any would serve you well, the Model 10 with the 3” barrel stands out. With good self defense loads it will do very nicely on night stand duty. The three inch barrel is long enough to shoot well at the range and short enough to used as a concealed carry piece. The round butt grip frame allows for round butt grips or round to square butt conversion grips. Good luck and whatever choice you make will be the correct one.
