Why do SW 340s & 360s have...

Because people have attempted to use 115 gr bullets in them. The bullets pull out under recoil and lock up the cylinder. I don't like airweights with less than 158 gr cartridges due to that. That or, S&W has Rugeritis.
 
Yep, it's true. My 340 pulled out rounds 4 and 5 of 125 grain .357 mag after firing rounds 1 through 3. It bound up the cylinder.

I do suspect, though, that the ammo wasn't crimped well, but then again, there was a good amount of recoil and torque.
