My wife had a M640 357. I shot it once with midrange 357 ammo and it wasn't too bad at all. I put a reduced power rebound spring in it. I really liked it but after a while she decided it was to heavy. She has a LC-380 now. IMO if you're going to shoot your snubbie a low a steel frame may be a better choice. I handled a Ruger LCR last year and the trigger pull was great.
