The website says:
Built for use with suppressors, the P-10 C Urban Grey Suppressor-Ready has an extended/threaded barrel with 1/2×28 threads and is clad in our distinctive Urban Grey.
Clad makes it seem like the frame is coated some how. My urban gray pistol, if coated, is the best paint job I have ever seen. Inside the mag well is perfectly smooth and uniform in color.
I’m ok with a cerakote finish, but would like a definitive answer if anyone knows.
