They're roughly similar, but with slightly different tolerances & performance.
(WE and TM at least, can't speak for Stark)
WE fit & work in a TM, and give it a lot harder kick. CO2; I'd be worried about damaging the pistol.
TM mags fit in a WE, but don't seem to have the 'oomph' to cycle the slide reliably.
This is going off my pair, one TM one WE with two of each brand of mags; bought second hand & TM mags 'upgraded' with Nineball routers (Possibly worse than stock tbh, but don't have originals to compare).
