IMHO, there is nothing that tops the Model 19/66 of the 2 1/2" persuasion.

...if you ever try a 3" you will retire your 2 1/2....
My two main carry options are Commanders in .38 Super and 4" N-Frame Smiths, most in .41 Magnum.
Which I carry depends of where I am and what the primary problem might be...
