During the 80's and even into the 90's Colt's Enhanced Govt. Models came with rubber wrap around grips. Some of these had a really fine pebble like texture and others were checkered rubber. They both had a silver Colt medallion. I'm trying to track down a set of the one's with the pebble texture. Is there anywhere other than a gunshow I might be able to track some of these down? Thanks for your help.
