I have a 4046 that I bought new when they first came out. I like the gun, it's been completely reliable. I'm kind of partial to S&W DAOs. I don't shoot the gun a whole heck of alot, since I generally prefer my 5946 and 5943TSW and 9mm Glocks. If you get it, just make sure the first thing you do is replace the recoil spring with a fresh one. Stainless steel S&W 3rd Gen. autos will run damn near forever, but, since you don't know how many rounds have been through it, it's better to be safe.
