SW99 is Melonite over stainless steel, P99 is Tenifer over steel. The former does have an edge over the latter since they improve the lubricity, wear and corrosion properties of the base material.
Tenifer/Melonite are trade names for the same process (Tufftride is another), all owned by the Dufferit division of the HEF group (not Glock). That's the German division of a French mulit- national corporation.
Considering both are made on CNC (computer numerically controlled) machines to the same specs, doubt it matters as much as some think where the machines are or who pushes the buttons on them... unless you are a union man/woman!?
