All this suppressor talk has got me curious, is there a definitive guide on how a suppressor works? The basics of course are easy enough: a series of chambers to capture gasses that lessen the report of the firearm. However what exactly are the details? Does chamber shape matter, does the size, or number of chambers matter? Can you make a single expansion chamber, and achieve good enough results for simple hearing protection? Looking at the various design cutaways posted earlier, its clear most designs follow a basic: large initial chamber, followed by a series of muzzle facing smaller chambers. Does having the initial chamber matter? Does the following expansion chambers need to be angled toward the on coming gasses? Obviously a lot of suppressor design is a trade secret, and each company will jealously guard its design all while telling you the other guy's can is scrap metal. So what is the go to book, or article, or youtube video, or forum post for suppressor mechanics, and design?
