Thread: Full barrel suppressor vs partial overbarrel/end forward

Have seen some full length (from receiver all the way past muzzle) overbarrel suppressors in medium calibers, but they don't seem that common. Would this be because the extra expansion chamber room in the full length suppressors is unneeded in most calibers as well as the extra weight? I can understand the pros and cons of the partial overbarrel and barrel forward suppressors, just never hear full barrel suppressors discussed.
