Several posters have implied that the OP is familiar with Glocks. His OP says he carries a .357 Mag revolver and says nothing of having ever fired a Glock. Just to be clear.
Ummm...he says right in the first post that he has been carrying his G19. He never says anything in this thread about carring a revolver. All he mentions is that he wants to know what caliber is comparible to a .357 magnum.
