The Ruger Vaquero is a sturdy,well made gun and is very popular with Cowboy shooters. If you choose to shoot Vaqueros,and shoot with two hands,then you would bee in the Traditional class,which is far and away the most popular shootind class in SASS. If you choose to shoot with one hand,then you would be in the Duelist class.
The difference between a Vaquero and a Bisley
is the shape of the grip frame,the hammer and the trigger. The Bisley was designed to be a target pistol shot with one hand. Go to Ruger Firearms
to see the difference,and to SASS Home Page
for a listing of the rules and different shooting catagories.
