I have a S&W model 19-7, 4" barrel that I payed $425 for about 2 years ago. I run predominately .38 special through it with the occasional cylinder of .357. I would say you would be fine at 1500-2000 mid-level loads per year.
The cracked forcing cone issues you hear about with the model 19 is due to the lightweight, high velocity .357 loads. Stick to 158 gr, mid-level loads and you should be fine.
Life is too short to not buy the handguns you want.....or think you gotta have.......or is just pretty......or a good deal.......(insert reason here)
