SW 317 .22 Jamming Problems

It is not uncommon to find S&W .22 revolvers with chambers that are out of spec, generally too tight chambers lead to the symptoms described.

The simple and practical solution is to get a .22 revolver finishing reamer and bring the chambers into spec or close to spec.

All of this polishing, brushing and fiddling is just a bandaid that doesn't fix the real problem.

Ejection should only require light pressure with one finger, and the revolver should be able to run 500 rounds without cleaning or sticky ejection.

Send it to S&W, your local smith or self-rescue.

Smiths who specialize in S&W will tell you the same thing, they might even tell you that about half of new 617s suffer from this to some degree.
