BudsGunShop.com - Finish?

Wilbur, The slide is stainless steel. The grey finish is cerakote. When this color in this model is gone it is gone.

Wilbur, it is essentially a Cerakote coating to over Stainless Steel. It is actually moderately durable. Some actual owner discussions here : https://czfirearms.us/index.php?topic=101546.0

CZ called the finish "Urban Grey finish". I believe this model is discontinued and there's not much information out there. The urban grey finish wearing significantly more than black. Everyone I know with the gray ones has a ton of visible holster wear. This is why they stop making it. I hope this helps.
