27-2 Cylinder is loose

[rere]

The cylinder on my 27-2 has a bit of rotational movement(more than I
like). The cylinder stop and cylinder stop notch show some peening, although very little. The cylinder looks fine and it and the crane are well fit to the frame. What's my best course of action before sending it in.

You can get an oversized cylinder stop, S&W item # 03775.

How is the timing and rotational movement with the trigger pulled?

 

[Bullseye Smith]

You need a Smith to install the stop - unless you know how?

Cylinder stop

Does anyone know where is it possible to order the oversized cylinder stop mentioned by "snw19 357".- Thank you all

I agree with Bullseye. The cylinder stop is important in the function and timing of the revolver. Sometimes they just fit right up and sometimes not so easy, especially if there is a difference in the width of the notches. If you are not trained, it might be better to send it to the factory and have them check out the whole gun as well.

Unless you have a significant carry up problem, this doesn't require any work. Nearly every smith revo on earth has some play in lockup, even most new guns. It has to be pretty severe before it affects accuracy.

Numrich gun parts. And they definitely have to be fitted but it's not that hard. Order the Kuhnhausen manual at the same time as you order the stop and you will see how to fit it in the book.

BTW: a little play in the cylinder can be good, allowing the bullet to center up entering the forcing cone. Adding a wider stop may eliminate play, but it may not be centered on the bore axis because wear in the frame slot is on the right hand side. So, installing a wider stop move the cyinder's lockup position slightly. Not a big deal, but may not be centered anymore (you have to check with a range rod).

Brownell's has oversize cylinder bolts and hands or you can get them from the S&W parts dept. I like to get a couple of each and play with things. I then look at the fouling in the forcing cone to see it the chambers are centered on the barrel axis.

Save the originals in case you aren't quite as good as you thought.

Great point! Pete

Thanks Gents, It's a hair looser than my others, but dead-on, I'll wait for a problem before I start looking for a solution to one.

Thank you Tom and Bountyhunter, it is very clear
