Does revolver barrel length determine recoil same ammo

Does a 6 inch barrel recoil less than a 4 inch barrel for the same model gun and ammo? If so, why?

That's not the answer your looking for however.

Go find a Dan Wesson mdl 15 357 that has several barrels. It takes about 60 seconds to swap barrels. Try the same loads in a 2 inch, 6 inch and 10 inch. The longer barrel WILL give you a higher bullet speed, but it is offset by the increased weight of the longer barrel.
I deer hunt with a DW using 185 gr hard cast solids over a case full of 2400. In a 4 inch S&W K frame it is painful. From A DW with the heavy 10 inch vent rib barrel, it is MUCH milder.
with a longer barrel, the small increase in velocity isn't enough to overcome the increase in slide mass. so yes it has more velocity but it has even more weight. pretty much a win-win situation except for trying to stuff it under your armpit or everyone would be using full size pistols.
then there's the issue of 4" vs 6". with any of the common semiauto calibers (380ACP, 9mm, 40SW, 45ACP, 357SIG) they have smaller case volume than 10mm and Magnum revolver cartridges. therefore they run out of gas after 5" or so. so when you get to 6", like before you are getting more slide mass, but you did not have much if any increase in velocity (like 12 ft/s or whatever) so you got everything to decrease recoil and nothing to increase recoil.
4" to 5" has a difference.
5" to 6" has a larger difference than 4" to 5".
4" to 6" has the most difference. of course.
unless you are Bill DeShivs and you have nothing but revolvers!
Mine don't have slides...
I have fired at least 100 small pocket pistols or derringer or pepper boxes - from the original Rollin White through to today...
Many of the diminutive and short / light pistols even in seemingly innocuous chamberings like .25 rimfire or .32 rimfire will literally try to spin or rotate around in your hand and seem difficult to control or keep hold of...
But those are overall balance and weight issues - combining small size and limited contact surface...
But I think that such small pistols should be considered separately from the general question you have presented...
