Señora Sies
From Halopedia, the Halo wiki
Señora Sies was a modified M6-series handgun, used by Ignatio Delgado.[1] According to Delgado, the stock had been replaced with oak wood, which was very scarce on Madrigal, and had been carved into "a piece of art" over the course of several weeks by his uncle.
Delgado had to trade the weapon with ODST Major Faison, in return for his more powerful Battle Rifle, as Faison lay dying on the Infinate Spoils. After Faison's death at the hands of Zhar, the pistol is assumed to be lost or destroyed.[2]
