I have several firearms, but my favorite by far is my Sig Sauer P229 with four (count em' 4) 18 round magazines.
I am about the same size as you and this gun fits my hands beautifully. It is deadly accurate (typically all rounds in a 2" center at 25 yards). Plus, it has three extra 18 round magazines.
Not all P229s are available this way. You may have to special order it.
Mediocrity dominates over excellence in all things... except excellence.
