AUTOMATIC PISTOL, CAL..45, M1911 AND M1911A1 2. The sighting bar is used in the first sighting exercise because with it small errors can be easily seen and explained to the pupil. 3. The eyepiece requires the pupil to place his eye in such position that he sees the sights in exactly the same alignments as seen by the coach. 4. There is no eyepiece on the pistol, but the pupil learns by use of the sighting bar how to align the sights properly when using the pistol. 5. The removable target attached to the end of the sighting bar is a simple method of readily aligning the sights on a bull’s eye. (b) The instructor explains the open sight to the assem- bled group, showing each man the illustration of a correct sight alignments (fig. 9). (c) The instructor, using the open sight, adjusts the sights of the sighting bar with target removed to illustrate a correct alignment of the sights. He has each man of the assembled group look through the eyepiece at each of the sight adjust° ments. (d) The instructor adjusts the sights of the sighting bar with various small errors in sight alignment and has each man of the assembled group endeavor to detect the errors. (e) The instructor describes a correct aim, again showing the illustration to each man (fig. 9). He explains that the top of the front sight is seen through the middle of the open sight and is raised to a height so that its top is level with the outside edges of the open sight and just touches the bottom of the bull’s-eye so that all of the bull’s eye can be clearly seen.
