My dad picked up a used Colt Trooper in .38 about 40 years ago and it became mine after his death. Just recently took it out to the range and fired it for probably the first time in 25 years. Performed great and very accurate. It is my understanding these were pretty standard police sidearms and I've got to assume there are a good number of tem out there. Does it have any particular value other than a nice old revolver that is shootable?
