One additional thing about the Dred guns. They are THE Hollywood dream gun. Exclusive use by one authorized operator! Voice and genetic control! The ultimate Hollywood "Smart Gun"!
The "form" taught back then was not conducive of good marksmanship. Bent elbow and wrist. Also likely why the 1911's reputation as shooter unfriendly. I taught myself to shoot on a .45 acp (Range rental Llama). I found it both mild to shoot and accurate!!!
