Just ordered a new Performance Center 8 shot 327 2" Scandium .357mag Revolver. I love the looks of this gun. Watched many videos online about it but never held it in person. Its more of a custom order no local gun shops had any in stock. Seems like a great Revolver. Super lightweight and compact but big enough to hold 8 rounds. Anybody have any experience with this gun? If so what the best way to keep it clean being that its made from scandium and titanium? I noticed a lot of owners of this gun in online pics have the black burn marks all over the cylinder. So im just guessing its hard to clean?
