I was at the range this morning and one of the handguns I had with me was my 317 Kit Gun with 3 inch bbl. I find it a fun little shooter. The only modifications to it are some very nice wood grips I bought off ebay (around $10.00 IMC) that are designed for the round butt J frame and the grips give it a more square butt look and feel. They fit great and are bigger than the stock grips and feel to me so much better than the S&W rubber grips. They improved my accuracy for sure.
I had some 22lr Aguila Interceptors and also some CCI Mini Mag 40 grain with me. Now the 317 is not a target gun. Its more of a true, in your pocket, woods walking, Kit Gun, and with its light weight and 8 round capacity it fills the job well IMHO. It will deliver minute of pie plate accuracy at 10-15 yards and for a kit gun that should be adequate. Over time my double action trigger pull has eased quite a bit. At 30 feet I can put all 8 rounds in a paper plate, firing double action, with either the Aguila or the CCI. The CCI Mini Mag is a bit more accurate to dead center than the Hyper Vel. Interceptors, but the Aguila rounds are quite powerful for a 22LR and penetrate well into wet pack. My 317 also handles Stingers quite well. The 317 is very light and handy and I do carry it right in my front pants pocket, out of sight. The 317 probably won't break any records for accuracy (I got used to the Hi-Viz sights) but with practice and frequent use I believe it will prove to be a nice little plinker and kit gun and that's what it is best suited to do. At least it did for me. Your results may vary. I do try to keep my 317 very clean so after a couple thousand or so rounds, it is still reliable every time. and never had a FTF. They are pricey for sure. The new (coming soon) stainless S&W 63 with 3inch bbl. should be a great kit gun. Another good choice for a kit gun would be the Ruger Bearcat. Good luck with your choice.
