If we ignore sight radius (ie have a red dot or scope), I believe anything past 4 inches will shoot as well as anything out to 12". Velocity will be different of course, but I have a Pardini SP, Pardini GT and Les Baer PII that will all do 1.5" groups at 50 yards with proper ammo and none of those has a barrel longer than 5".
