A police trade-in S&W 5906, all stainless steel, and all over GunBroker for $350 and in the CDNN catalog on page 27 for $299 . It is easy to dress one of these carried a lot shot a little Stainless pistols wear with a green scrubbie and a set of houge grips. for $400 you will have an accurate all steel 15 shot 9mm.
Agree on the 5906, I've owned a police trade-in 659, which is the 5906's predecessor, since 1988, and even after more than 10K rounds above whatever the cop shot through it, it's the most accurate pistol I've ever shot, just too bulky and heavy to conceal or it would be my carry gun. The only drawback is that Smith seems to engineer at least 50% more parts into their autoloaders than any of the competitors. At under $300 bucks, I might spend some money with CDNN myself.
