Grip angle is something that I approach fanaticism about and I found this piece from Ammoland to be interesting. https://www.ammoland.com/2018/08/5-...0_6f6fac3eaa-72ee33efe5-7170233#axzz5N77tP39w The infamous Glock grip angle that many hate to love and love to hate was something that Gaston felt was an extremely important element of the pistol's design. In order to more fully understand the thought process behind the grip angle that Gaston chose, one has to understand that military doctrine of the time was to shoot a pistol with one hand, body bladed to the target. Gaston invited several guests to join him at his vacation home in Velden, Austria and asked those guests several questions about what they wanted from a military sidearm. One of the design elements that Gaston intended to figure out was what angle the grip should be. The Glock Grip Angle is measured as shown. He passed mockups of pistols made from pieces of wood nailed together around and asked his guests to aim at something with both their eyes open, as well as their eyes closed. The thought process was that aiming the new sidearm should be instinctual and shouldn't take much effort. The consensus among his guests was that a grip angle of 22-degrees was ideal, but Gaston later reduced the angle slightly somewhere in between 20 to 21 degrees.
