The P365 followers look great, and keep looking great with use. The harder material and shape of the follower prevent gouging and the finish looks great even after use. Here are some photos of a follower with over 300 rounds run through it this outing and it still looks like new.

The brass and dirt wipe right off with a gun cleaner. The follower still looks like new. There is a little bit of finish wear where the slide stop contacts it, right on the edge of the ledge that can be seen below:
