http://www.thesurvivalistblog.net/prepare-survival-carbine/ This is for a 357 Magnum Lever Gun, but IMO the HP carbine would be a better and cheaper starting point, and carry pistols to match! SWEEET! Imagine how we can mod an HP to get similar features! They also have some really good ideas on using the sling for some storage. This all adds weight of course, so it may hinder CQB. This is more of an "on the go" or Bug Out mod.
