Overview
Overview
This 8 mm delayed blowback pistol loads through the top and has a hinged magazine door on the butt. The pistol has a separate bolt release and safety. The production delay between patent and military trials allowed comparisons with other self-loading pistols, and the Salvator Dormus was considered inferior to its competition. The designers abandoned this project; and few pistols survive. The Bundeswehr Museum of German Defense Technology in Koblenz has one of these specimens in its collection.

• Illustration — The A.J. Ordnance Thomas.45 uses a similar delayed blowback operation that delays the slide when fully gripped. The Salvator Dormus pistol uses an unusual grip delayed blowback operation actuated by the trigger pull, when fully pulled back delays the slide otherwise would be a simple blowback operation.
