I own a Baby Eagle 45 with an assortment of magazines. They are a little "double-stacked" and some hold 10 rounds and the others only 8 rounds. They look like identical mags and all measurements are the same except for the springs. The 10 rd. spring is longer than the 8 rd. mag.
What causes the difference in the number of rounds they will load?
