Is "head" distance when using sights determined by the model itself?

[pd3 25]

I've noticed a fairly significant difference between the distance the perspective seems to have between some addons and the default BI pistols.

I would like to know if this is determined by variables in the config file or if it's information that is part of the model itself that tells where the perspective should move to when you are aiming down the sights.

I personally find the distance ridiculously close and find that unlike certain addons, the default BI pistols don't lend themselves to close quarters use at all.

I would like to make my own config variants of these pistols if the "head" camera distance is changeable via the config as opposed to it maybe being defined with the model itself.

Any info regarding this would be appreciated.

Darn, that sucks.
