Forgot to add, about wear patterns:
AVOID liners. They're great at first, but they attract dust & grit, which means they eventually turn into fine-grain sandpaper to take your finish right off.
Kydex tends to wear sharply on just a few points.
Leather gives a more gentle wear, but it wears
everywhere.
Pick your poison. If you use the gun out of a holster, that will affect the finish no matter what you do. Start using the word "patina," as in, "I enjoy the well-worn patina on a gun someone has used a lot."
