Pros
A nice and more believable alternate to the default Magnum.
Cons
When in dark areas or absences of light, since there's no real shine on the skin, the Magnum becomes a huge black silhouette on your screen. Not to mention it can also appear "flat" in areas with lighting too, since there's not any kind of real shine to show depth and definition of the weapon's features. It just a huge shadow covering it, hiding any detail the texture has.
It's not too often I find Magnum skins that I spot and try out, however the fact that there's a severe lack of anything to make it visual appealing via definition of the model's shapes and features through lighting is leaving me wanting. Shadows "Overshadow" too much from what I've seen.
