I picked up a used GEN 3 Glock 23 a couple of weeks ago and had the slide refinished in OD Green. It is the alter ego to my OD Green framed G19! I also added some Meprolights to my G23. Here are some pics:
I paid $45 to have the slide refinished. I had it done by a guy named Justin (I believe that was his name) who works at Strictly Shooting in Evansville.
