I'm glad I don't have to choose just one additional S&W .357 Magnum, as they are all great guns in their own right. The Model 19/66 have sleek proportions that look and feel "right". I wouldn't want to hammer a constant diet of hot magnum loads through mine. Why wear them unnecessarily when the L frame 586 and 686 exist. My 6 inch 586 is my favorite .357. Gorgeous, accurate and durable, though for daily carry or hunting I would choose a 686.
