The Sig Sauer MPX Off-Duty 9mm carbine is a pistol-caliber carbine with a 16-inch barrel, a folding stock and a 35-round magazine (brand part no. WRMPX-16B-9-35). The finish is black. Putting a 16-inch barrel on the MPX gives a longer sight radius and a little more velocity from every 9mm load than the short-barreled MPX versions, while the folding stock keeps the carbine compact for a vehicle or a range bag. It is a practical choice for range days, home defense and anyone who wants a 9mm that shares its ammunition with a handgun.

Key Specifications

• The chambering is 9mm, a common and affordable round that shares ammunition with most 9mm handguns.
• Barrel length is 16 inches, a length that gives a longer sight radius and better velocity than a short barrel.
• The stock is a folding stock, which shortens the carbine for storage and transport.
• Capacity is 35 rounds from the included magazine, which keeps range sessions moving.
• The finish is black, a practical, low-glare color for a defensive carbine.
