There is a reason for the step in the 9mm chamber. The round headspaces off of the mouth of the case. As far as a precise measurement of the magazine, no problem. I've got a set of calipers. I've got four different kinds of magazines, so here are the measurements.

My FXO - 1.069"
Swiss - 1.0695"
70's Mauser - 1.065"
Mec-Gar - 1.0625"

I measured from the middle of the back of the magazine to the middle of the curve in front, inside to inside dimensions. Interesting variations...
