I am trying to get an idea of the capacity of the handle on the Shadow IV. I noticed that the Shadow III is described in another thread as "holding a Arc AAA perfectly". This gives me a very good point of reference as to the capacity of the Shadow III handle (assuming it is an accurate description). I was wondering if someone could give me a similarly effective description of the handle capacity of the Shadow IV? Handle capacity is of a major concern for me. I would like to get the handle capacity as large as possible but I must also keep the blade at 5.5" or less for legal reasons. Also I should note that if the Shadow III and IV are the same then I would probably go with the Shadow III as 4" is plenty of blade for my purposes, however a 5.5" blade is certainly workable if it would mean (roughly) 25% or more handle capacity over the Shadow II. Thanks in advance.
