Approximately 2,500 Camp Perry pistols were marketed by Colt between the years 1920 and 1941. This unusual model was created by replacing the 6-shot cylinder of the .22 Officer’s Model Target with flat “cylinder” containing one .22 cal. chamber. Camp Perry, Ohio is the site of the annual National Rifle and Pistol Matches.
It’s a target gun, used specifically and only for shooting a target as precise and accurately as possible. This one feels like a revolver which is what people used at that time. But it’s a smaller caliber, long barrel, and all the moving parts beside the trigger and hammer removed.
