If you find a nice model 57 I suspect you will really like it.
It is one of many which I wish I had been able to keep but at the time had no choice but to sell it. It was about as accurate as it is possible to make one.
On the negative side, I could never tell the difference between it and the model 29 as far as recoil Boy now that I think about it, those model 29s were also great.
My problem is that I would want a pristine S&W 57, 58 or 29 and then I would not want to carry it. What I really NEED is one with cosmetic damage, but good working condition.
