The only problem K frames have with .357 mag. is the lighter bullets shot from them. The thinner part of the forcing cone is prone to wear with the lighter bullets (110gn).

By "forcing cone" I mean the first part of the barrel that has a thin underneath section that may crack.

For some ballistic reason I don't understand the heavier bullets (158gn) don't cause a problem.
