Now, they don't actually say it is .357 magnum OR .357 Sig. They just list the caliber as .357. However, since no one could say (with a straight face) that .357 Sig rivals or exceeds .357 magnum in terms of performance (energy and knock down power), I assumed they were talking about .357 magnum.
The velocities of the two calibers may be similar but the smaller .357 Sig (125 grain vs. 158 grain for the magnum) packs about 100 ft-lbs less energy at the muzzle.
Also, I am pretty sure I have seen .357 magnum glocks in stores and at gun shows.
