"Finally, I have been seriously looking at the Sig's. They just seem to be quality. I haven't ruled out HK's though. "

The Sig models are well known for accuracy and reliability. Although I personally prefer pistols with a cocked-and-locked capability such as the Govt Model (don't rule out a Kimber Compact if you are not uncomfortable with a single action), the HK USP series, or even a Taurus auto.
