The Defender configuration uses an 18-inch Winchester Proof Steel barrel with a fixed cylinder bore. It is a non-vent-rib, non-threaded setup intended for wide pattern performance, paired with a brass bead front sight and no rear sight.
Winchester's Speed Pump rotary-bolt action drives fast, positive cycling. The extended magazine tube runs to the muzzle with a knurled cap and is cataloged at 7+1 capacity.
The receiver is aluminum alloy with a black finish and anti-glare serrations on the top. The barrel and magazine tube wear a blued finish, complementing the practical, duty-style layout of the Defender series.
Chambered for both 2.75 and 3 inch shells, this shotgun offers flexibility across common 12 gauge loadings. The hardwood stock features a straight comb and a ventilated recoil pad, with a 14.0 inch length of pull and a cross-bolt safety at the trigger guard.
Manufactured in the United States with New Haven, Connecticut marked on the rollmark, this Model 1300 Defender reflects the features that defined Winchester's close-quarters pump platform.
