I am looking to change my smooth service trigger for the serrated target type. I have the trigger and wanted to get a ballpark on what a smith would charge to do the swap? Thanks

Well has anyone done the swap themselves? If so could you post some info? Thanks

Just do a search on youtube for "S&W revolver trigger" or similar.
There's a ton of how to videos there to help.

The swap is not a big deal .all you have to know is how to disassemble the revolver.
My M29 came with the 'target' [1/2" grooved] trigger but I immediately changed it for the 'combat' [3/8" smooth ] much better I think for target, hunting or defence .
If you have a knowledgeble gunsmith do it he could smooth things up too.

A gunsmith should not charge a great deal to change a S&W trigger.
While you do get cases where the trigger needs some fitting and adjusting, "most" of the time it's a direct drop in fit.

WHAT a gunsmith will charge depends on the going rates locally, and how reasonable the gunsmith is on his charges.

If you'd like to tackle it yourself, all you really need is a copy of the Jerry Kuhnhausen shop manual and a Brownell's Magna-Tip screwdriver set for the S&W revolvers.

The shop manual was written as a training aid for student gunsmiths and shows everything about how to work on the S&W revolvers the FACTORY way.
This is the best S&W gunsmithing info available and the best money a S&W owner can spend. It goes into great detail on fitting new parts like triggers:

Depends on the era but at worst two small pins have to be punched out and then driven back in. Shouldn't take a gunsmith with any experience more than 15-20 minutes. The new MIM triggers don't even have the pins.

Buy the books and tools. This is a excellent opportunity to learn some gun mechanic skills. This is a pretty easy swap with little to no fitting involved.
