What is the difference between a Blackhawk and a Vaquero?
A Ruger pistol that is designated a Blackhawk has adjustable sights whereas the Vaquero has fixed sights. You may own a New model Blackhawk, meaning your pistol has adjustable sights. Otherwise, you would have a New model Vaquero which has a key lock in the grip frame but fixed sights. However, the Old model Vaquero and Old model Blackhawk do not have the key lock feature. Thankfully, the grip frames for either model Blackhawk and the Old Vaquero are the same so the grips are interchangeable.
