Happy to hear that things worked out well. I have a PILE of wrong parts that Taurus has sent to me to go with my PT 1911, which is a nice gun, but I finally just gave up on Taurus, because they couldn't come close to sending me what I needed, and paid for. It was another sight issue, like yours.
The warranty and service experience for me will, unfortunately, steer me away from an otherwise pretty nice product line. I sent them a post, very nicely worded and polite, about my experience.
One post I read several moths back was from a gentleman who worked in the US parts and service center for Taurus. He said that they had parts all over the place, the floor, the benches, under racks, mislabeled, etc. It is no wonder that they struggle in this area.
