I've done a significant amount of reading on various handgun forums and I have come to the conclusion that I want a 3" S & W handgun. The gun will be used for general purposes: some hiking, some carry, some plinking. I think that I like the model 65 or model 66. The model 60 seems ok, but the m65 and m66 have the advantage of 6 shots rather than 5. I will want to shoot .38's, .38+p's, and .357 rounds. What about the older model 13 and model 19's? What about the newer model 586 and 686's? Could someone who knows S & W handguns offer an opinion, as well as offer price and availability of used vs. new models? Also any reliability concerns with any of these models? Thank-You!
