What is ap vs sp pistol?

Answer 1

In NRA terms, this is Air Pistol and Standard Pistol. These are types of pistols used in International style pistol matches. Air Pistol is usually a 60 shot slow-fire match. Standard Pistol generally consists of 20 slow-fire, 4 x 5 shots in 20 seconds, and 4 x 5 shots in 10 seconds (rapid rife). In addition, on my collegiate pistol team we also competed in Free Pistol (FP). That is for light trigger, single-shot pistols with advanced grips. SP and FP use .22 rimfire ammunition.
