A friend of mine built a Bedford school barn gun that has no triggerguard. The trigger slants back, and lays close to the wrist. Instead of drawing back on the trigger you grasp the wrist and squeeze upward. It works fine, but he has been bared from some events with it. He actually killed a nice deer up in Oregon with it. The game warden that validated his tag was inthralled by the simplicity of his gun.
