Mossberg Sweeps October’s Top Five New Pump-Action Shotguns

Mossberg occupied all five positions in GunBroker’s new pump-action shotgun rankings for October 2026. The 590 took first place, followed by the Maverick 88, 590 Shockwave, 500 and 590A1.

The sweep included a change at the top. The 590 moved from second in September to first in October, while the Maverick 88 shifted from first to second. The 590 Shockwave and 500 both climbed into the Top 5 from lower positions.

October’s Top 5 New Pump-Action Shotguns

The table follows the source report’s category assignments, including its placement of the 590 Shockwave. That reporting category is not a legal classification of an individual firearm.

590 Moves Ahead of the Maverick 88

The Mossberg 590 gained one position to lead October’s new pump-action category. The Maverick 88 remained in the first two positions but finished one place below its September ranking.

The two models exchanged first and second place while remaining ahead of the rest of October’s field. They were also the only entries in the new pump-action Top 5 to finish within one position of their September ranks.

590 Shockwave and 500 Enter the Top 5

The 590 Shockwave rose from sixth to third, gaining three places. The Mossberg 500 made a larger move, advancing five positions from ninth to fourth.

The 500’s five-place rise was the largest gain among the category’s October leaders. The 590 Shockwave followed with a three-position gain, while the first-place 590 rose one position.

590A1 Completes the Mossberg Sweep

The 590A1 ranked fifth after finishing third in September. Its inclusion completed a Top 5 made up entirely of Mossberg entries, despite its two-position decline.

The 590, 590 Shockwave and 590A1 accounted for three of Mossberg’s five positions. The Maverick 88 and 500 supplied the remaining two, giving the October list representation from several separately reported Mossberg model lines.

The Used Category Had a Different Leader

Mossberg’s new-firearm sweep did not extend to the used pump-action ranking. The Remington 870 Wingmaster led that category in October, followed by the Winchester 12, Remington 870, Remington 870 Express Magnum and Mossberg 500.

The Mossberg 500 therefore appeared in both condition-specific Top 5 lists: fourth among new entries and fifth among used entries. The used pump-action Top 5 retained the same order as September.

Five Positions, Not a Market-Share Percentage

Mossberg’s sweep means it held every position in the new pump-action category’s published Top 5. It does not mean that Mossberg accounted for every new pump-action transaction on GunBroker, or that models from other manufacturers recorded no sales.

The October result is a complete set of leading model positions within one category and condition. It does not establish a ranking across all shotgun action types.
