I have a model 1917 that has gone out of time. The gun was rebuilt by S&W in 1974 at which time the barrel was replaced, it was roll stamped, and reblued, so it's not a collector item. Just want to turn it into a nice shooter

I read the thread on parts interchangeability, Parts Interchangeability between N-frame Generations , and I just want to make sure I've got everything correct before ordering parts.

The article says that modern hands can be used in pre-war guns. Does that mean I could order an oversized hand for a 625 and it will work in the 1917? If not, which model should I look for?

I have already placed an order for a Wolff extra-power cylinder stop spring mentioned in the article.

Also, the chambers in my cylinder are rather pitted, are there any newer cylinders that will swap into the 1917?

Thanks for any help.

As long as it isn't a Brazilian or a late commercial model, a modern hand will work. The Brazilians and late commercial models had the hand with the ramp that disengaged the hammer block in the side plate.

Before you buy anything, I'd recommend that you measure the width of the hand that is now in the revolver. When it was rebuilt in 1974, an oversize hand may have been put in then. If so, your options become limited. Regular hands run from about .091 to .094". Oversize hands run from about .096 to .0985". When a revolver goes out of time, a hand that is about .002" wider will usually bring it back into time.

Sometimes if the hand is on the narrow side of regular, an oversize hand can be too big. That's the second reason I recommend measuring the one that is in there.

All six shot N-frame hands are alike.

As to the cylinder, a 25 or 625 cylinder can be made to work. The problem is the modern cylinder will be left hand ejector threads and the 1917 has right hand ones. The 1917 ejector star can be fitted to the new cylinder but it gets complicated.

If you'd like to discuss further, PM me and we can talk offline.
