VA, agree it's up to the user. Helped a lady at the range recently who had little experience, she had more snags using her Ruger 40 than the revolver she also was trying. The 40 was a large gun for her hands, etc. etc.
No doubt a little practice will get a shooter accustomed to the controls and if it fits her hand, thats key.
J vs K, true the little Js are going to come back more. I run a K 3" and Magnums are no problem, though know a 686 L is better yet if your going to burn some ammo. Heavier and larger though, not a great 'carry' piece.
