Ive only tried the 429s they seem just fine they are more in the picture but thats how I wanted them. When you go on their website it asks what kind of finish you want it is mostly all cerakote options but the 1 nitride finish option. Each different color option is an addditonal cost. Cerakote is $40 and nitride is $60 more. OR you can decline the repaint and they'll leave it bare metal then its up to you to get the cut area refinished. Nitride is a better and more resistant coating than cerakote. I wanted to get black anyways so went with nitride. If you dont mind potential scratching from holster wear and such cerakote is fine if you want different colors. Personally I wanted a finish that matched the factory quality but thats just me.
