Actually, it's only like 51 or 52 parts, some of which can be tedious to reassemble!
Leather versus kydex is almost like which caliber is best; you'll get endless discussions on both. Kydex is slicker, lighter, and longer lasting then leather "in general," but leather is prettier, often more comfortable. Which wears the finish more is debatable. Much depends on whether the holster is designed to fit that particular model gun. The difficult part is finding quality holsters for the -82 to begin with.
