The Winchester SXP Defender is a 20-gauge pump-action shotgun built for home defense and tactical shooting sports. This compact 18-inch barrel model chambers 3-inch shells and holds up to five rounds in the magazine plus one in the chamber—plenty of firepower in a maneuverable package. The fixed cylinder choke and fully chrome-plated bore deliver wide, consistent patterns with buckshot and are equally reliable with Foster-type slugs, making it a versatile choice whether you're running multi-gun competitions or standing post at home.
Winchester engineered the SXP Defender for real-world handling. The composite stock and ribbed forearm won't shift in your grip during rapid fire or under stress, and the non-glare metal surfaces stay quiet and low-profile. At 6 pounds and 38.5 inches overall, this pump shotgun stays nimble in tight spaces—a significant advantage in a home defense context. The inertia-assisted action cycles reliably and feels smooth from shot to shot, and the brass bead sight keeps your reference point simple and fast.
If you're serious about 20-gauge home defense or looking for a faster-handling shotgun for three-gun matches, the SXP Defender delivers proven Winchester reliability in a form factor that favors control and speed. It's the kind of gun that rewards training and delivers when it counts.

Frequently Asked Questions
What choke does the 18-inch barrel have?
The SXP Defender comes with a fixed cylinder choke—no constriction—which produces open, wide patterns ideal for buckshot at close range and works well with Foster-type slugs. This choke cannot be changed.
Is this shotgun good for home defense?
Yes. The 18-inch barrel, quick-handling composite stock, and 5-round ready capacity (plus 1 in chamber) make it well-suited for home defense scenarios. The wide buckshot patterns at cylinder choke and low overall length enhance maneuverability indoors.
Can this shotgun shoot slugs?
Yes. The fully chrome-plated barrel and cylinder choke deliver good accuracy with Foster-type rifled slugs, making the SXP Defender effective for hunting or distant defense applications where slugs are preferred.
How many rounds does it hold?
The SXP Defender holds 4 rounds in the magazine tube plus 1 in the chamber, for a total of 5 rounds ready to fire.
