It has come to my attention that I do not currently own a j frame Smith, a situation which I intend to remedy at the earliest opportunity. I had the chance to examine a sixties vintage model 38, but I couldn't convince the owner to part with it. Although I didn't have one of the newer models on hand to compare, the little gun seemed smaller, trimmer and more refined. Is this just my imagination? Did Smith & Wesson ever change the dimensions of the J frame, or maybe it's an optical illusion caused by the matte finish and larger synthetic grips on the newer guns. Would the older style wood grips still fit the newer 442, 642 or 638?
