All TargetLog field notes in gear & equipment — drills, gear, and guidance for ISSF precision shooters.
ISSF rules require a minimum total trigger pull weight of 500 grams on 10m air pistols. The trick is distributing that weight between the first and second stages so the gun feels predictable, passes equipment control, and lets you release the shot cleanly.
A correct sight picture in 10m air rifle comes from a properly adjusted diopter, the right front aperture, and consistent eye position behind the rear sight.
ISSF Rule 8.6.1 permits 10m air pistol athletes to compete in ordinary sport clothing. Shooting jackets, special trousers, and stiff footwear are all prohibited in air pistol events.
Adjusting your rear sight is how you move shot groups on target. You change the sight, not your hold. Each click on your pistol moves the point of impact by a specific amount, and learning your pistol's click value lets you correct group center from any target you photograph.
A properly fitted grip aligns the pistol with your forearm bones so you hold it with minimal muscle effort. The result is less wobble, better trigger control, and more consistent scores across a 60-shot match.
ISSF 10m competition requires .177 calibre (4.5 mm) wadcutter pellets. The right pellet — in the right head size and weight for your barrel — can mean the difference between a 570 and a 590 qualification score.
Your first ISSF competition air pistol needs to meet strict rules — 4.5 mm calibre, 1.5 kg maximum weight, 500 g minimum trigger pull — but the most important factor is finding a grip that fits your hand.
