Iver Johnson Pump Features The Iver Johnson Pump runs a pump action system chambered in 20 GA with a 3 chamber so the shooter can cycle either 2-3/4 or 3 shotshells through the same gun without any adjustment. Its 26 vent rib barrel has a smooth bore which keeps the gun versatile for shot loads while the vent rib helps dissipate heat and reduce the mirage that can disrupt a sight picture on a hot day. A 5-round magazine tube built for 2-3/4 shells gives the shooter extra rounds on hand for walking up birds or working a dove field without reloading as often. A fiber optic front bead sight pulls ambient light for a sight that stands out against brush and sky backed by an intermediate bead sight along the rib. The stock and forend are cut from walnut and finished with checkering at the grip and forend for a secure hold even with wet or gloved hands. A rubber butt pad is fitted to the stock to soften recoil impulse over repeated shots a welcome feature on a 20 gauge meant for long days in the field. At a 14.5 length of pull and 46 overall length the gun is sized for a natural comfortable mount for most shooters. Finished in black over walnut the Iver Johnson Pump brings classic pump gun styling and reliable function to hunters shopping for a dependable 20 gauge available for sale at GrabAGun.
