Yep- ALL 357 Magnum revolvers will also fire .38 Special- and also .38 Long Colt, and .38 Short Colt (last two are kinda scarce) They are all the same diameter, but different lengths and power.
All of those ".38s" are really shooting bullets that measure .357 in diameter. Confusion has to do with the change over from a bullet that was the same size as the case (like a .22 LR) to later cartridges that the bullet fitted INSIDE the catridge case.
The .38 Special ammo is less $$$, and less recoil/ blast.
What we have here is... failure- to communicate.
