Factory fit, factory quality - SIG SAUER P226 9 mm Threaded Barrel

As expected, the barrel dropped right in (you need to remove the thread protector first). Accuracy was as good as the barrel that shipped with the gun. Reverse threaded (against the rifling) so it will keep tight, though I did have to re-tighten it several times over the course of a 200-round session. Maybe some lightweight thread locker if a suppressor isn't going to be used. Overall, I'm very pleased.
