Congrats on getting you old Commander back..
Looks like whoever you sold it to has taken good care of it.
Though I prefer SS 1911's I do like blued ones too... here may be reason why:
Years ago, I let a friend handle my blue Gold Cup, and .thought I'd wiped it off well before putting it away.
Imagine the look on my face when some time later, I pulled it out to find a perfect thumb print rusted over the Gold Cup "trophy" on the slide.
This was back when I was working FT, had 2 young boys, & was taking care of elderly parents that had serious health issues, so not much time for shooting
The slide rust had corroded deep enough that it couldn't be sanded & refinished..so I eventually ordered a new slide.
Lesson learned. Maybe that's why I rarely shoot that G.C. ?
