I only use 7 rounds out of habbit, most of my mags are 7 rounders, I do have a couple 8 rounders somewhere, but only load seven in those when they are used, so it's always seven. Only carry one extra mag with me, so I only have access to 14 rounds altogether. Too old to switch to 8 rounders now, been counting rounds in my head for too long during practice. I practice dropping the mag after six shots and reloading before the pistol is empty. Just 8 more to go after that.
