Both will weaken the brass for reloading but lots of KBs have occured with factory ammo. Lots of KBs have also occured with many different makes of handgun and in both revolvers (fully supported chambers) and in autos. The Glock chamber looks like an attractive red herring!
Please do detail your experience with revolver KBs not directly attributable to overcharges. I've seen KB'd revolvers, but they were always associated with double charges of fast powders.
