Spring powered air pistol shooters would only compete against other spring powered air pistol shooters in this competition. These air pistols are sometimes referred to as "kickers" due to their classic recoiling action.
Some spring powered air pistols (such as an FWB Model 65 or 80 etc) have been made recoilless, and when they were the "top dog" in target shooting during the 1970's, their main rivals were the Walther LP3 and other Single Stroke Pneumatic (SSP) air pistols that also enjoyed a recoilless action.
These recoilless pistols will have their scores recorded separately and against each other - but they will not have their scores recorded against any of the "kicker" scores.
