Consider a used S&W model 13 with a 3" bbl. Most folks don't need adj. sights on a snub, and the S&W 13 3" is a classic .357 Snub, the old FBI gun. Mine, loaded w/ .38 wadcutters, is a perfect trail / small game gun, small and accurate as hell. And with 125 grain .357 Mags, is like a fistfull of fire and brimstone.
