I'm fast becoming a big fan of Zero Halliburton cases, mostly due to the one I've borrowed from Decius. This one might qualify as dual use. I could envision it working well for other weapons, such as guitars. I think this has made my want list. Why the hell do I always seem to develop such expensive tastes? The exceptions don't add up to the desired. There is just something about a brief case that can stop a carbine round that's, well, sexy..
