Jimmy, the 2 1/2" model 19 is one of the must have classic "cool guy's" revolver. I'm lucky enough to have several and with one exception they will be the last firearms I ever give up.
I also have several 2 1/2" model 66's and one of these will the LAST firearm I give up. The advantages of the stainless steel are just about impossible to beat.
So if you want a working revolver go with the model 66. If you want something to add to the collection that can be used from time to time go with the classic model 19.
Or better yet, buy one each
