I stopped by a police supply store in the area and they had in the used gun/police trade-in case some Ruger Police Service Six revolers. Wondering what they are (GP-100's, Security Sixes, etc.)? They were stainless, 4" half lug barrels, fixed sights, hogue grips, and GP-100 style cylinder release buttons. Is this just a renamed GP-100? They were asking $250 for them.
