If you want a flush fit mag then get 7 round mags. If 7 rounds in the mag doesn't do it for you then get a Tripp Cobra or a Wilson ETM 8 round mag. I prefer the Tripp 8 rounder over the Wilson ETM.
So the Wilson 47D 8 rounders won't fit flush on a closed slide but a Wilson 47 7 round mag and the Wilson ETM 8 rounders will?
