Joe,
Because it is tradition on this forum to muddy up the waters by introducing a new variable into the equation!
Actually, I like both the 2nd and 3rd Dragoon. I keep telling everyone I want the 2nd model because the square-back trigger guard gives it a bit of an old timely look. Jus' tryin' to hang on to as much nostalgia as possible but being practical about it by eliminating the 1st model as a contender.
Tell ya what OP...since you asked lets settle it this way...If you like round trigger guards get the 3rd model Dragoon. If you like the look of the square-back trigger guard of the Walker then go for it. Now, wasn't that easy?
