The proprietor at a small LGS told me a story comparing muzzle flip between a 3" and 4" Ruger SP101. He said that the 4" actually had much more flip because the extra barrel length increased the mechanical advantage of the lever formed by the barrel and grip -- more than negating the additional barrel weight. He claimed there was a significant difference, enough to make the 4 inch hard to shoot.
Well, some additional leverage makes some sense, but I assume he is exaggerating (based on other stories). And I haven't noticed a similar difference shooting 6" and 4" revolvers (though I have not compared the same model/contour with different barrel lengths on the same day or same box of ammo).
Maybe the significant difference is due to the smaller frame ...
I've assumed additional barrel length/weight more than counter acts any additional leverage.
