I have a 617-6, with 10 round cylinder, and it has become one of my favorite range guns. It is 6", which I prefer for the accuracy. The longer barrel gives a better sighting radius. If you are strictly going to punch holes in paper at 5 - 10 yards, and never shoot longer distances or do any competitions, I would also consider a Mod 63, (J Frame), with 4" barrel, but specify "target" grips. The standard J Frame grips are too small to do any serious shooting. They are made for concealing.
