Here is my current lineup of .357 mag revolvers. Of the three, I find the Model 19 to be the most useful, and the most appropriately sized for the caliber.
The big single action is an Interarms "Virginian Dragoon", which was produced from the mid 1970's into the early 1980's. It was meant to compete with the Ruger Blackhawk. Unfortunately, it was half again as expensive, and didn't stay on the market for long. It was manufactured in Alexandria, Virginia, and touted as the only hand gun produced in a Confederate state since "The War of Northern Aggression".
This particular example is the subject of a good deal of debate today. I actually purchased it from the back seat of a Seattle police car from a cop friend with an FFL. I'm still friends with his son (he passed many years ago) who owns a local gun shop. Interestingly, many will try to tell you that they never produced a Virginian Dragoon in this caliber. I've even had shooters tell me "it must have been re-barreled, and the cylinder made from a blank". They don't believe me when I tell them I bought it new. Kind of a useless gun, really - it's the heaviest handgun I own, by far. My other two Dragoons - one in .44 mag and the other in .45 Colt - are much lighter, due to the bigger holes in them, and pack a lot more punch. Fun to shoot, though, and great for new shooters, since there is almost no recoil.
Then, of course, there is the very recognizable Colt Python. Another fun to shoot but pretty worthless gun. I wish it were a 4", that would make it more useful to me. I bought this one from my brother a few years ago, who bought it new in about 1980 when he was in the Navy. It would make a good duty gun for a cop, but for the rest of us, I think it's just a fun plinker.
The Model 19 is my favorite. It's actually somewhat useful, since it is so small. It's concealable under a dinner jacket, and really easy to carry when back packing. I do prefer a bigger caliber for that, but for a guy happy with a .357, it really can't be beat.
The grips on the Python and the Model 19 are, by the way, from Steve Herrett. They are known as the "Roper" style, named after an S&W employee who designed them in the 1930's. Steve makes these to fit your hand - you send him a trace of your hand, and he builds them accordingly. I would highly recommend them.
Anyway, that's my lineup. I love shooting these things. Little recoil, cheap, and way more accurate than I am.
