So, as far as people's experience is telling me, any gun that feels right will work. So money is the issue. That's one of the reasons I went with wanting a Sig, and not a Kimber. The Kimbers, so I'm told, are awesome guns, and beautiful by the way. And the colt and springfield are functional, inexpensive relatively speaking, but are not as pleasing to the eye. The Sig seems to be in the middle of the two: great quality, looks good, especially custom, and is only about $1100, versus $2500 I've seen for some Kimbers. Thanks everyone for the advice.
