Why Do Different Models Seem To Have More Kick?

Springs vary, but I agree within a small variance they are the same.

You are for sure correct about the longer bbl, but the key is the higher velocity- which gets "squared", thus increasing the recoil impulse- which is somewhat off set by the slightly heavier bbl.

I do not agree about the stock- more weight = less felt recoil,
it is just physics; of course if you put it on your shoulder, you would feel the recoil in a different way and place- maybe that is what they meant?

Note that Eric said with "the same luger ammo"; implying all were in the same caliber(to me at least), but it matters not if all are 9mm or all are .30- the long barrel will shoot "farther" than the short bbl; all else being equal(like the angle at which fired).

Before someone says some of those are 9mm and some .30- each form shown Could be in either caliber- but just likely did not come that way when made.

The question is meaningless if different calibers are compared, as the premise of "the same ammo" is out the window!
