I'll throw another vote in for the SP2022, it is one of the more highly tested pistols out there, I believe France bought over 250k to arm its military/police.
I've got an SP2022 in .40, and while it is a little heavy for a polymer, it is really a great shooting pistol. Also, the trigger is very, very smooth, in fact the double action is smoother and lighter feeling than my P226.
I carry mine sometimes when I'm out in the woods, and with a decent holster, it really carries very well. The only downside to the SP2022 is that they only come with one magazine. Its not too big of a deal though, I watched cdnn and picked up 3 more mags on sale for 20-something each. CDNN seems to run this kind of deal on a reoccuring basis, so I'd bet you could buy extra mags for a similar price.
The bottom line is , the SP2022 really should cost more, but the French government has already done us the favor of covering Sig's development and tooling costs. Now it looks like the company can sell them off for their straight per-unit costs + some % profit.
