I carry a G30 now which allows 11 rounds. When Im not carrying my G30 I am carrying my G23 which gives 14. I only carry these because I shoot them best and they give me a good caliber with sufficient capacity. The extra mag that I carry is for the G21 and G22 respectively giving me the extra rounds.
To me, there is always the possibility of having a confrontation with a BG or BG"s, no matter where I go. Therefore, no matter where I go, I want what I shoot best with me at all times..... and I am glad that it holds more than 5 rounds.
