I had the same dilemna when I was looking for a little revolver for my lady. what I ended up deciding even though I know she would never shoot 357 magnums I decided to get the magnum any because well... it will shoot 38 ammo too. when she uses it I load it with 38 +p hydra shoks and when were at the range Ill feed a few mags through it. I suggest just getting the magnum that way if it ever comes to it you wont second guess your choice. good luck
