All of the 617's are great pistols whether they are a 6 shot or 10 shot versions. I have a 6 shot no dash with 6 inch barrel and it's a wonderful shooter. There are lots of people who like the 4 inch version better then the 6 inch but that's a matter of taste because most all 617's end up being primarily range guns. You could use one for self defense but there are many better options.

They are a heavy revolver when compared to the model 17 because the 617 all have the full barrel under lug and stainless is heavier then blued steel. They are a very strong revolver and I doubt that you could ever shoot one out.

Used versions sell very quickly so if you find one you like at a decent price I would buy it. The 617 no dash came with S&W combat grips like the ones pictured below and after the no dash they shipped with rubber grips starting with 617-1. At 617-5 in 2001 they introduced the internal lock.
