When the Sole Survivor and Deacon return to the site to recover a lost prototype of an unknown device for Doctor Carrington, the Deliverer is recovered by Deacon and offered to the Sole Survivor.
This old handgun was recovered and restored by Tinker Tom for Railroad heavy agent Tommy Whispers, called the 'Deliverer.' He still had the pistol in his possession when he was killed at his faction's old HQ, the Switchboard when it was raided by the Institute's forces. The fixed barrel also acts as a guide rod for the recoil spring. The handgun has an exposed hammer and a double-action trigger mechanism. The shorter grip, barrel and reduced magazine capacity result in a smaller size than other pistols of a comparable caliber and made better suited for concealment.
It features an exposed hammer, a traditional double-action trigger mechanism, a single-column magazine and a fixed barrel that also acts as the guide rod for the recoil spring. In terms of design, it is a small, concealable pistol.
A cutting edge pre-War design, the Deliverer combines firepower and subtlety in one, compact package.
