SIG Sauer MPX K Off Duty 9mm Pistol, 4.5″ Barrel, Black, 35-Round, Off-Duty LE Only

Description

SIG Sauer MPX K Off Duty 9mm Pistol, 4.5" Barrel, Black, 35-Round, Off-Duty LE Only

The SIG MPX K is SIG’s 9mm piston firearm. The MPX runs a short-stroke piston and AR-style controls on 9mm, with magazines that are SIG’s own MPX pattern.

It does not take Glock, P320, or AR-15 magazines. The top rail is optic-ready. A factory optic is not installed. Pistols ship with SIG’s folding PCB. The SBR uses a stock and needs NFA paperwork.

This configuration

Confirm you are eligible before you order. If you want the commercial MPX K with the Timney trigger and folding PCB, that pistol is listed separately on this page. Off-Duty sales are limited. After those checks, this pistol ships to a licensed FFL. If you want a 4.5 in. MPX with a folding stock, that is the SBR, and it needs NFA paperwork.

What ships

A factory optic is installed only when this page says so. This item ships to a licensed FFL. See the SIG MPX collection.
