Okay. I need some schooling on this. I guess the better way to explain it would be that the throat is less deep (or something, hehe). For example, I have a 124g 0.356 round nose loaded to a coal of 1.250. I drop it into my m&p9c barrel and the first band on the bullet makes contact with the throat and the bullet still has 0.06 left to seat flush. I drop the same bullet into the barrel of a kahr cm9 and it passes the plunk test. I used a test bullet 38 special and measured the amount above the barrel chamber and the m&p9c is 0.06 shallower than the cm9 when seated on the throat.
