I got mine yesterday. Sadly, the night sights are nearly dead on mine. I turned out the lights and they could just be seen. I am checking to see what they cost to "recharge" or whatever it's called.
The gun is in real decent shape, just carry wear on the outside, and I would guess about 500 rounds through it, judging by the barrel wear compared to a friend's 4506. One of the two mags has a couple of rust spots on the outside of it, but it seems to be fine otherwise. I don't know if I will keep it, as DAO isn't my cup of tea, but I will be shooting it Sunday. I expect it to work fine. It came pretty clean, I just wiped it down with CLP, and took it apart enough to inspect everything.
Now I have a 5906 coming!
