I have been a huge fan of almost all firearms chambered in the 41 Magnum cartridge since I bought my first one accidentally in 1980.
This 15 or 20 year old group photo shows about half of the 41 magnums currently in my collection
The 3" snub nose revolvers were a fantastic firearm. I can not recall how many years I carried mine
If you have not yet cleaned and lubed the firearm then it is way too early to decide if it needs to be sent off for an action job. Also before choosing a gunsmith you probably would need to decide what the revolver will be used for and what level of trigger work you want done.
The bulk of my revolvers have stock actions, smoothness comes simply through the repetitiveness of pulling the trigger the parts we're into each other and everything gets better. Action jobs typically make that natural process occur faster
Also remember when asking about opinions to do or not do something, here on the forum We have an extremely high percentage of purists as our active discussion base.
However out in the real world, the purists make up a teeny, tiny portion of the Smith and Wesson buying public. So our opinion of what will sell or what will work on the used market is dramatically different than what Smith and Wesson's buying public are consuming
The Smith and Wesson Performance Center may not be the shining star that it once was, but it is still not a bad place to get work done. There are also dozens of extremely skilled Revolver shops around the US that are still taking firearms in for work. Pinnacle High Performance, Cylinder & Slide, Clark Custom, Gemini Custom, Mag-na-Port, Ron Horvath, and many more
I will use Mark over at Pinnacle for those things that I do not do myself
