S&W has had my 340SC since October. I was never contacted by them at any point after they received it, and my calls to S&W CS got either "I don't knows" or being told that I'd be called (wasn't, of course). The frame lug that retains the cylinder wore down through normal use, a known problem on the scandium J frames. Generally though, a replacement frame is used, the gun is replaced, or there's some offer of a discounted revolver voucher or whatnot.
Nope, in this case after months of silence I get an email from fedex that I have a shipment inbound. This shipment missed its delivery date and spent a week in fedex pending hell, but eventually it got there (OK, that last part isnt the fault of S&W but I'm still gonna whine about it!). Opened it up, just form with a short note that it's beyond repair. Overall, extremely disappointed with this experience. These aren't cheap revolvers, Smith continues to build them with major known problems, and now when they break it's not getting made right (had a S&W 642 crack a frame that was replaced quickly a few years back, sad to see that's no longer the procedure).
I've seen tons of threads of issues with recent smiths, and they make me nervous, but I always had "oh S&W will make an issue right" to fall back on, now that I don't I think I'm done with anything Lock or newer and will stick to Ruger when I need a slightly more modern revolver.
Also, found one last downside to the Scandium frames. When they're broken, they don't even make that good of a paperweight!
