High Standard Model 21 20 Gauge Pump Shotgun, 27" Vent Rib, 3" Chamber, Poly-Choke – J.C. Higgins Era
Built in the 1960s for Sears under the J.C. Higgins name, this High Standard Model 21 combines a 3" magnum chamber with a factory ventilated rib and adjustable Poly-Choke—features unusual for its time. Modest factory scroll engraving on the receiver flats, solid steel construction, and an aftermarket Decelerator recoil pad make this full-size 20 gauge both collectible and shooter-friendly.

What’s Included
- High Standard Model 21 20 Gauge pump-action shotgun with 27" ventilated-rib barrel and Poly-Choke
The Model 21 represents the final pump shotgun marketed by Sears under the J.C. Higgins brand. Manufactured by High Standard (code 583), it predates the 1968 Gun Control Act and therefore bears no serial number—an authentic hallmark of its era.
A 3" chamber sets this gun apart from most contemporary 20 gauges, allowing the use of modern magnum loads. Combined with the adjustable Poly-Choke, it offers quick, tool-free choke selection from open to full, expanding its versatility in the field.
The steel receiver wears factory scroll engraving panels that add subtle character without compromising the Model 21’s workhorse reputation. An oval “HS” proof mark confirms High Standard manufacture.
An aftermarket Decelerator pad not only tames recoil but also shortens the length of pull to about 12", making the gun more accessible to smaller-statured shooters. The original hardwood stock retains factory checkering, while a long, flat-sided fore-end with diamond-pattern checkering provides a positive grip during rapid cycling.
