I have a Galco paddle leather holster with a thumbbreak. It leaves tanning oils or something on the corners/edges of the slide after carrying with it. I wipe this stuff off with a silicone cloth at the end of the day. I realize that eventually this will lead to holster wear. I am OK with some honest wear, but I also don't mind minimizing the amount of holster wear. Anyone have any pics or information as to what these chemicals do to a Glock finish? I also have a Fobus Evolution paddle polymer holster. The only wear that it makes on the gun is some friction marks on the trigger guard where it uses pressure to retain the pistol. I am wondering if I would be better off using the Fobus because it won't affect the gun's finish like the leather. Any pics of pistols showing some holster wear from polymer holsters? Like I said, I don't mind some holster wear. The gun is a SD tool, and not a safe queen. I would like to, however, minimize the wear just a bit. Which holster should I use with that in mind? Thanks.
