It will be a little snappy with 357 , but will be a blast to shoot 38 special. If you get it - use snap caps and practice firing about 300-500 times to get the trigger pull to lighten up. If you can get for $400 or under it is worth considering.
I like the 650 a whole lot for CC. Silverstring's advice (above) is excellent and if followed will only enhance the experience of owning a 650. I'd "pull the trigger" and obtain one if you can get a favorable price. You will not be sorry.
