If your one of those fellows traveling around the seedier parts of town and are sure you will need a Hollywood magazine that never runs out then go with the g30. If not and your simply looking for a CC weapon just in case, look at the G36. A single stack Glock in 45ACP and a good little shooter with a big daddy punch. Not as pretty as the Sig or Kimber or any other gun for that matter because after all it is a Glock. But bless their little hearts Glocks are priced to own.
I have large hands and the 30 kills my fingers. I can only grip it with 2 fingers and the trigger guard hits my trigger finger every shot. Get a FNS 40 or 9 or glock 19/ 23. Mid sized conceal ability. Or you could get a commander or office model 1911. That would be better than any glock any day.
