Para shooting Paralympic shooting, also known as "shooting Para sport", is an adaptation of shooting sports for competitors with disabilities. Paralympic shooting first appeared in the Summer Paralympics at the 1976 Toronto Games. Para shooting is internationally governed by the International Paralympic Committee. To help establish fair competition, a shooting classification called Para-shooting classification is in place for the Paralympic Games. The events mirror to some extent the shooting events at the Olympic Games. Air Pistol is typically shot from a seated position with the pistol unsupported. The amount of back-support permitted is determined by the athlete's level of disability. The Air Rifle events include Rifle "Standing", which is shot seated like Air Pistol, with variable levels of back support. "Prone" Rifle uses the basic prone shooting position utilising a sling for the supporting arm, but is shot rested on a table with the athlete seated either in a chair or wheelchair. Competitions using factory and service firearms Shooting competitions for factory and service firearms, usually called Service Rifle, Service Pistol, Production, Factory or Stock, describe a set of disciplines or equipment classes where the types of permitted firearms are subject to type approval and few aftermarket modifications are permitted. Thus the terms refer to permitted equipment and modifications rather than the type of shooting format itself. The names Service Rifle and Service Pistol stem from that the equipment permitted for these types of competitions traditionally were based on standard issue firearms used by one or several armed forces and civilian versions of these, while the terms Production, Factory and Stock often are applied to more modern disciplines with similar restrictions on equipment classes. Factory and service classes are often restrictive in nature, and the types of firearms permitted are usually rugged, versatile and affordable. In comparison, more expensive custom competition equipment are popular in more permissive equipment classes. Both types of equipment classes can be found within many disciplines, such as bullseye, field, practical and long range shooting. Plinking Plinking refers to informal
