[QUOTE="Shadowrider, post: 3080885, member: 3099"] I've seen several guns that had a PVD finish that was worn all to hell. Kydex is "static'y", and that attracts dust. Dust particles are UUGELY larger than the coating's thickness. All it takes if for that dust particle to dig under that micron thickness coating and there you go. Scratched. These coatings are engineered for surface abrasion applications where "like" components are sliding or rolling on each other in controlled (generally not open to the atmosphere) conditions. They have been used for over 30 years as cutting tool coatings and only "relatively recently" on machine components. Also if the coating is porous and diamond hard, that just means that the pores that fill up and hold oil leave a pathway for moisture to get in. That oil isn't an "impenetrable barrier" by any stretch so in the pores themselves there is no hardness. FYI, I personally ran a ASTM B117 salt fog cabinet 24/7/365 for several years. I have years of experience with various engineered coatings in the aerospace and oilfield industries. All these coatings are great for their various purposes (usually wear resistance) but keeping guns looking pretty isn't what they excel at or are even developed for. Real world is different when you start drawing from a holster, if you leave it in the safe and take it out to look at it once a year to look at it, then yes, they are all fabulous. I'm not saying to ignore the specs and testing, but just keep this in mind when looking at them. There's a chit TON of marketing behind them. [/QUOTE]
