I realize this is a S&W forum so there will probably be a bias. However I am considering a 642 Performance Center and a Ruger LCR. The only thing that interests me about the LCR is 9mm (my chosen duty ammunition). I will be carrying either as a backup on my ankle. I cannot carry anywhere else as my bodyarmor manufacturer states not to attach anything to it. Opinions? In revolver I can carry S&W, Ruger, Colt and Kimber. Colt and Kimber seem large for ankle carry.
