A stainless Taurus PT1911. That thing was a turd. ILS (in the hammer) broke after 80 rounds. I replaced the hammer with a Nowlin Pro only to have the ambi safeties start falling out shortly thereafter. It was the only gun I've ever had rust in a humidity controlled safe. No other gun has ever had even a speck of rust. The MIM parts on the Taurus started rusting with the quickness. It was not terribly accurate either.
I sold it a gun show and have never been so glad to see a gun go.
