I have a Ruger American Pistol that I bought some time ago but haven't had the chance to shoot yet. Turns out, it was one of the affected guns: https://www.ruger.com/dataProcess/APRetrofit/?r=banner Even though the gun is basically NIB, I figured I'd send it in for an inspection anyway. Mailed it in last Friday and got it back today. It now has a new black Nitrided barrel instead of the original silver-colored stainless barrel. Are the black barrels standard for new production guns?
