ToddG's post on p-t.com got me thinking. As part of the PPC (Practical Pistol Course) at the range back home, there's a left-side barricade string, shot weak hand, but with the strong hand on the pistol too.
I can't recall any drills mentioned here or at p-t.com that suggest shooting weak hand, and not weak hand only.
Why not? Does it just not offer any advantage over strong hand, both hands, even when shooting around a left-side barricade?
