SIG Sauer has successfully adopted the marketing strategy long used by high-end German automakers, particularly Porsche; offer lots of option packages, some of which can more than double the base price for changes that are arguably minor when assessed individually.
Some commentators will argue that the motive is good- give buyers what they want, something that seems unique and personal. Others will argue that it's a cynical ploy to maximize profits and rake the buyers over the coals.
Both arguments are correct to a degree.
If you don't like it, buy the base model, or a Camry/Glock.
