[QUOTE="osok-1k, post: 2565782, member: 106259"] There were bare areas where they were hooked the parts with hangers and it didn’t wear well as compared to DLC. I did a complete 1911 slide, frame and all small parts except springs, it was smooth to cycle but didn't last very long. I know a guy who builds high end race engines (Nickens Bro's Pro stock), he does wrist pins in DLC but polishes them to a 2 micron finish. I checked some from an engine he was freshening up that had about 8-10 runs and I could barely perceive a wear line as compared to a new one ready to install. If one considers the pressure wrist pins are subjected to in pro stock 9k RPM race engines, I was impressed and began looking into DLC for firearms. I have a Curtis Axiom in DLC and it started rusting in some areas and has very early signs of wear on the raceways, magazine port and feed ramp as well as the bolt body and lugs (200-300 bolt cycles), so I'm going to Cerakote it when I do the barrel. I believe as in most things that the person doing the process has much to do with the end result. For that reason I'll likely not buy another Curtis but rather Terminus for three lug actions. To be fair to Curtis, I did not reach out to them about my concern and they may have refinished it with apologies but since I do my own Cerakote, I decided to go that route. I'm sure that Parker Trutec would do a first class job which is who I would use if sending something out for DLC. [/QUOTE]
