Since I've owned this fine revolver it's had a sticky cylinder release. It turns out that the center rod has mushroomed and get's stuck in the hat of the extractor. I am a mechanic by trade but definitely not a gun smith. I feel comfortable replacing it but parts are sketchy at online gun stores. I would like to order parts from Smith & Wesson or just sending it to them for a once over. Nothing on the SW website about ordering parts. Any advice would be appreciated. Jeff

CALL S&W Customer Service and explain what you need. 800-331-0852, then listen for the prompts.
 
Gun Parts Corp (aka Numrich) sells factory S&W parts. Their web site is excellent and their shipping is quick. Brownells also sells many stock parts. For that matter so does Midway.

(Don't forget the backward thread on the extractor.)
 
If your 19-3 is a 2.5"barrel the center pin is 074710000 and if longer the part number is 074720000. A quick search and Midway has both, the shorter is $7.19 and the longer $7.59. Brownells wants $11.49 and Numrich (Gun Parts Corp.) wants $12.01 used and $16.11 new.

Don’t forget the center pin is a fitted part so you will likely receive one that is too long and you will need to install, push the pin from the bottom equal to the ratchets and file what is sticking out from the top. If you buy a used pin and it is too short - then that is no good…
 
Due to the position of the shoulder on the center pin, it may be difficult to find the correct one for your dash 3. The new ones I've ordered recently don't have the right length at the rear, where the pin interfaces with the breechface.

An alternative to finding and fitting a new pin is to carefully remove the excess material that has been peened out on the front edges of the existing pin. After cleaning up the end of the pin, figure out how much length is needed to make the pin interface with the locking bolt properly. When the thumbpiece is fully depressed, the front end of the center pin should extend forward to even with or just a bit forward (.005"-.010") of the end of the extractor rod.

If the pin is a bit short of reaching this desired length, you can shorten the end of the extractor rod a bit, and re-profile, or remove material from the extractor rod collar in the assembly. Removing material from the collar will make the entire extractor assembly, except the center pin, shorter when it is re-assembled. This will move the extractor rod back the desired amount, and correct the issue with the front locking bolt catching on the end of the extractor rod when the thumbpiece is fully forward. The collar can be easily shortened by laying it on a stone, and while holding it with the fingers, working the collared end back and forth on the stone surface.

Another possible and easy way of solving the problem that precludes the necessity of purchasing and fitting a new center pin.

Why do so many of you insist on directing someone with a parts question to Brownells, Numrich, E-Bay, etc, especially after the OP has already been directed to S&W for the first choice? S&W charges less in most cases than any of the retailers, often will send small parts at no-charge, and not charge shipping! Or don't any of you know that? In this case he can possibly receive what he needs at no cost compared to the others that charge for the part plus shipping, which can result in the cost being possibly $20 or more compared to likely $0 from S&W. And all the retailers get their parts from S&W to begin with!

Try S&W first, then Jack First in South Dakota. THEN go to the others if these two can't provide what you need!

I've fixed a couple of these by removing the center pin and rolling the mushroomed part between steel plates (I used some old machinist's parallels).
