SIG Sauer P365 Semi-Automatic Fire Control Unit 9mm

Description

This is a serialized SIG Sauer P365 fire control unit, which serves as the modular heart of the handgun system and requires a background check for transfer. The unit features a steel chassis with a black finish and is fitted with a light-colored, flat-faced trigger. Key markings include the manufacturer and location SIG SAUER and NEWINGTON, NH USA on the right side, while the left side displays the serial number 66E768519 along with the number 11 and a circled T. A circled 16 is present near the rear of the left side, and the underside of the trigger shoe is marked 173-T-11. This lot consists of the fire control unit only; it is missing the slide, barrel, grip module, and magazine. Note - All firearms require a federal 4473 background check.

Condition

The steel chassis retains a high percentage of its black finish with minor wear visible on the contact rails from previous use. The flat-faced trigger shows no significant marring or scratches. Residual white lubricant is present around the trigger pivot and internal spring components. The action appears to function correctly with a crisp trigger break and reset, though we have not function-tested this firearm with live ammunition.
