Closer to the muzzle, above the trigger guard root is the weapon type designation MI9IIAI U.S.ARMY.

The personal mark of the assembly worker is located on the left side at the top of the trigger guard (3) and on the right side at the trigger guard root (1) and illegible at the top after being punched over by SILESIA dealer. The army verification mark P is located on the left side of the magazine release, on the upper side of the slide in front of the rear sight and also on inner parts.
The left side under the slide has the abbreviation F J A. of an Armament Service Colonel Frank J. Atwood, who commanded the acceptance of the pistols throughout their production. The cartridge ejection port on the barrel is stamped with caliber designation CAL..45 and the German eagle N.
The magazine corresponds to the manufacturer Risdon Tool & Die marked on the top of the magazine tip with the letter R.
The weapon also bears German acceptance marks of an eagle with letter N (Nitro) at the slide in front of the grooving and under the inscription MI9II AI U.S. Pat. ARMY on the right side. The abbreviation SA of the Silesia dealer is punched over the verification mark of the German testing laboratory Hannover in the form of a galloping horse. There is also a number 66 in a shield in front of it, which should represent the testing year 1966. These marks mean that the pistol was traded by the German company Silesia and should originate from a wartime delivery to one of the allies of the United States or could have been sold off after the war by the United States Army in Germany.
