I've owned dozens of colt replicas and all but a few of them shot high. I've heard several reasons for this, one being they were meant for long range shooting out to 70-100 yards. This is plausible since it isn't too difficult to punch holes in a five gallon pale with my 1860 all day long at 100 yards, however, I doubt most people of the day ever shot at those distances with a handgun, most encounters were likely within a matter of a few feet. I've heard lots of old west gunfights that resulted in partcipants clothing catching on fire from the muzzle flash. I've also heard that Colt deliberately set the sights so they would shoot high since, by most accounts, in a gunfight situation people tend to aim at the widest part of the body by instinct, this would have made it more likely to place a ball within the vital zone. I usually just aim low with my colts, but I have altered a couple by installing a higher front sight. All you have to do at this point is just file it down gradually until you get it hitting center. In any event, those Dragoons are a lot of fun to shoot.
