In my life, I have sold exactly two guns. One was a BPS I bought on speculation and flipped. The other was a Taurus 669 .357 mag that I bought myself for my 18th birthday and intended to keep forever.
The rear sight was cranked all the way one side, and it still would not shoot centre. The grips were never tight, and the gun frame would shift inside them. Any loads greater than .38 +P would lead to sticky extraction. Full bore .357 loads that worked great in my friends GP100 would lock the gun up tight, and actually caused a slight crease in the thinnest section of the cylinder crane. The mainspring was light and would only set Federal primers off reliably. Lead shaving in the forcing cone was chronic.
It was, in short, a piece of unmitigated feces, and I will never so much as pick up a Taurus again.
To fill in the data point: The gun was bought brand new mail order from LeBarons in April 1991. It was a 6" blued model.
