Good reminder. I too have been real religious about pulling the ol Mak (it's one of them there steel guns, ya know)outta it's kholster when I get home and giving her a little wipedown. So far this year I've been able to keep any rust to a minimum.
Another good lesson to note, do not use one of those cheap padded nylon things; did that before I found the kholster, it will absorb sweat and rust a gun like no other!
