For the original poster, it's a personal choice. To me, 6+1 is a bit on the meager side for capacity. Statistically, it should cover most defensive shootings, but not with a big margin. I would definitely carry a spare mag, and give serious thought/practice to reloads.
Personally, the move from 7+1 (XDs) to 15+1 (G43x) was worth some expense and a slightly larger footprint. (Also, the longer grip meant I won't pinch my hand so often on reload, which was keeping me from using the old gun in competition.)
