617 is not very good for teaching. It is very heavy and finger groove grip makes it impossible to hold for folks with smaller hands. I have it because it mirrors my 686+.
I used a 317 with 3" barrel and, while it is usable, DA trigger pull is so heavy many had trouble with it. IMO, the perfect training .22 is S&W17 (which is what I gifted my mother) and I prefer older version w/o heavy barrel. Accuracy is on par with 617 and the sahpe is much better. Taurus 9-shot .22 is also good for training but I am not convinced it is all that durable. That said, 317 would work, just not witht he snubbies barrel (again, better than nothing but muzzle blast and aiming difficultes would be considerable).
