If I could withstand an SW340PD, there's no way in hell I would fire it on the reg except other than with a few rounds of Speer SB to test it, to actually practice I'd get another similar jframe or a second one and beat that gun up in practice. IMHO those guns all have a limited service lifespan and the more rounds you put through it the closer you get to blowing it up. I've lost track of how many people have blown theirs up, there are at least two NES peeps that I know have blown theirs up, and I know a third guy not on NES that blew his up, too. (Actually his is kind of funny, when they repaired it, smith put a .38 SPL+P barrel shroud on it, but his gun is clearly a .357 magnum) No injuries, but the gun stops working after that shot. They pretty much all fail the same way. (the frame cracks near the crane area, whole thing goes out of alignment and cylinder stops turning) In between the horrendous recoil and bad long term service history, those things get a black cross/hard pass from me. I won't even fire one if offered, at this point, because they're so f***in painful. I'd much rather fire a 4" 500 S&W with log or nuclear loads out of it , or even my friend's Ruger Alaskan .454, than that little bastard. At least those two guns have some mass to them. After farting around with small revolvers there is no way at this point I'd go with anything below a SW640 or maybe one of these K6Ss. Sure it weighs more, but it is just as concealable and a hell of a lot more shootable than most of the uber-light revolvers are. Back when I had my SW640 I could even shoot heavy 357 out of it with the little boot grips on it, and while it was annoying, it definitely wasn't nearly as painful as a 340. The 340 is obnoxious enough that you'd have to offer me about $400 to pop off a full cylinder of 357 mag from it, before I'd even think about picking it up. Even then, I'd wear goves, and I'm going to take about 600mg of ibuprofen afterwards.
