9mm vs 11mm pumps

[Chris]

Take a pump apart, theres always gonna be bolt on stuff from almost every pump, like better things from one pump and better things from another, other camplates, plungers, cradles, LDA's to list a few... undertsanding what these do and why will help you pick a better one if you ever come accross another pump

Been reading plenty regarding pump mods, changes etc today.
Just to clear up terms.
Cradle - gov cradle?
Plunger - as in what most refer to as head size so 9, 10, 11mm etc?


Just a quick one are the leaver sets all a fixed length and require modification to increase travel, or do different pumps have different lengths?
