You don't own a pistol or a "Can".andy said:pistols, the few that are worth a crap, are the real deal, since they are the only type likely to actually BE THERE when you need a gun,and offer the sort of speed into action, silence, etc, that might let you get the job done.
A powerful centerfire pocket pc, and a silenced pocket .22lr, make up by far the most useful 2 lbs total wt of pistol you can possibly carry. Granted, the can on the M21 renders it no longer a pants pocket fast draw piece, but it can certainly still be very swiftly drawn, from IWB, concealed, or if wearing the backpack, from the top opening fanny pack (top left open) worn at the navel.
