I forgot to mention that I removed the ridiculous internal lock on my 340sc. The recoil forces are so extreme that the internal lock is almost certain to not operate as designed and tie up the works. I cannot personally recomend that anybody remove the idiotic internal lock, but there are plenty of internet helps if you Google "S&W internal lock removal". It does not take long if you're mechanically inclined
I have a 340PD and I like it because it is light enough that I will actually carry it with me. Yes, it can be punishing to shoot. When I take it to the range, I shoot one cylinder's worth of ammo and then I'm "done".
