I agree.
I have two scandium S&W 340PDs, and with premium factory 125-158gr+P .357 Magnum JHP loads, they are neither fun to shoot nor especially accurate or precise.
I'm not recoil-sensitive, but I've found that my examples of these little pistolas shoot more precisely with certain examples of .38 Special+P JHPs rather than any type of .357 Magnum (of which I tried ALL available factory examples in 125gr+P JHP), though a friend's 340PD (in my hands) did better with .357 loads than did mine, so it may well be specific to the particular gun.
In any event, I neither shoot nor carry .357 Magnum rounds in these little guns anymore.
I haven't shot the .44 Magnum S&W scandium version(s), but the only way to know if it hits consistently to POA in your hands is to shoot it.
