Hy-Score Pistol: short barrel vs long barrel

[45flint]

I have a large collection of Hy-score pistols 700, 800, Sportsters. The Sportsters and the 700s with their fake front barrel have barrels much shorter than the longer running 800 series. I was thinking about it and even with the shorter barrels they are concentric and therefore longer than many front barreled guns. Are the longer barrel 800’s actually gaining anything from their longer barrels? Can a spring powered gun gain power from the longer barrel? The sight radius with the 700 is the same as the longer barrel 800: is accuracy potential different or the same?

I have enough pistols to test the power question but I am finding variation is spring strength, especially my 700’s seem easier to cock but I have a Sportster that is one of my most powerful?
