What is the proper term for excessive rotational play on the cylinder -- both at rest, and locked in Single action mode?
Thanks!
Thanks!
Terminology?

- Start date
front to back is end shake - test with empty cylinder closed and trigger pulled to the rear

No front to back noted -- just excessive side to side rotational, as with an undersized lock. I know all revolvers will have some rotational play -- but how much is too much?

Surprisingly, there is not a rotational play tolerance specification for S&W revolvers.
Thoeretically, it becomes unacceptable when it allows a range rod to bang into the chamber mouth when tested for bore-to-chamber mouth alignment. That would be about 0.004"-0.006", or more than the depth of a rifling groove.

Honestly, I haven't fired it yet -- it was a brand new firearm that I had to send back the factory for a disconnected trigger linkage problem. It just came back from the factory repair center where they replaced the connecting rod, inner hammer, hammer sear spring, and hammer sear (no -- it isn't a S&W product...). The work order indicates that the gunsmith "refaced" the cylinder stop lever (it looks like metal was ground off of the lock). Supposedly, the GS fired 12 rounds of CCI .357 Mag ammo through the revolver and 12 rounds of Federal .38 Special with no problems noted. It does appear that it has been fired and not cleaned.
I feel that there is excessive rotational play -- and I am debating if I should just send it right back...

f&s,
I don't suppose (it's a new gun) that the notches in the cylinder look peened?
John Traveler referenced the range rod, I think you can get one for most popular calibers from Brownells.
I hope it checks out ok, I would shoot it with some mid-range loads before I shipped it back, avoid the hassle, if possible.
What's the brand/caliber?

No, the notches don't look peened.
It is a Chiappa Rhino 40DS (White Rhino) in .357 Magnum. I also own a 50DS (Black) as well -- and it does not suffer from the excessive rotational play. It is a very accurate revolver -- and extremely comfortable to shoot with full power loads...

Chiappa? Are they like a Taurus? Unfortunately its hard to diagnose a gun that's not a S & W. The lock up could be and most likely is completely different than a Smith revolver. Sounds to me like another gun with the quality control of the foreign companies we are getting pawned off on us more and more.

Well, since S&W copied Taurus' Judge -- and introduced the Governor, maybe they will copy Chiappa and the Rhino... 
Like I said -- the 5" Rhino i have is fine, I just felt that the 4" Rhino has too much play in the cylinder.
I've certainly had my share of unsatisfactory S&W's (even brand new ones) that had to go back for warranty repair...so, I don't feel any of the manufacturers are taking as much care with quality control as in years past.
I didn't mention the manufacturer at first because I expected there would be some comment. I simply wanted to get an opinion from S&W revolver folks about how much rotational play is acceptable in a revolver cylinder...
What I'm reading on most forums is "shoot it -- if it is accurate and doesn't spit lead from the gap, you're good to go..."
I'll run some semi-wadcutters through it and see what happens.
Thanks all for the input!

Do any of your local gun stores have Rhinos in stock? If so, you could ask to hand a couple new ones and compare the cylinder play to your gun. If yours seems noticeably worse, you may want to send it back again. Looseness in an action is something that can only get worse not better, though I say this with the caveat that I have no first-hand knowledge of Chiappa's design. Good luck.

I've got my own 5" model to compare this 4" model with -- they are noticably differentin the amount of rotational play. They're only a few hundred apart in serial number. I'll shoot it first since they've already run 24 rounds through it. If it turns out to perform less than I desire -- I'll send it back one more time for a fix - requesting that a new non-refaced lock be installed...
Thanks

My brother used to say to me " mess with the bull, and you'll get the horn."
Maybe the same goes for the Rhino,,
Good luck

I've started the process to get another return authorization from Chiappa to send the 40DS back in for warranty repair a second time...
I took the revolver fr a little test run. It is definitely "spitting" with lead bullets and the accuracy was poor compared to my other Rhino -- a 50DS with better fit and proper timing.
The turnaround time for the last trip to Dayton, OH was quite fast, so I am hopeful that they will make the necessary adjustments and return a properly functioning revolver to me within the next week or so.
