Best all around is the Model 19/66 with the 2.5" barrel. A very close second, in fact, virtually a tie, is the Model 13/65 with the 3" tube. Either is the "perfect packin' pistol" as gunwriter John Taffin is so fond of saying. Not too much weight, but has six shot capability. The 19/66 has adjustable sights and a shrouded ejector rod, and the 13/65 has fixed sights with an unshrouded rod. Can't go wrong with either one, and either is as valuable as the other.
