I watch both shows (this and Sons of Guns), but I like American Guns slightly more. No, not for the eye-candy.. but because it seems a lot less stressful than Sons of Guns. SoG has too much drama; maybe American Guns does as well but they don't show as much. Although Sons of Guns gets a whole bunch of stuff we could never hope to have in NYS (full-auto, supressors, etc).
Top Shot is another good show, although that has a ton of drama also. Top Guns is kind of an 'after-show' to Top Shot that brings in expert marksmen to give opinions on different firearms. Iain Harrison was on last week's episodes, and he is a HELL of a shooter.
