It highlights how manufacturers often leave unused space in the magazine tube, reducing capacity and aesthetic appeal compared to 20-inch counterparts. The discussion questions why this space isn't utilized to extend the tube flush with the muzzle for improved capacity and appearance.

Quick Summary

On 18.5-inch barrel shotguns, magazine tubes are often shorter, limiting capacity to 5+1 rounds. Manufacturers frequently leave unused space where the tube could be extended flush with the muzzle to add another shell, improving both capacity and aesthetics.

Frequently Asked Questions

Why are shotgun magazine tubes often shorter than the barrel?

On shorter barrels like 18.5 inches, manufacturers sometimes use magazine tubes that don't extend to the muzzle. This can limit capacity to 5+1 rounds, even though there's space to extend the tube further for better capacity and aesthetics.

What is the typical capacity of a 20-inch defensive shotgun?

A 20-inch defensive shotgun, especially models like the Mossberg 590, usually features a magazine tube that sits flush with the barrel. This configuration typically provides a capacity of 7+1 rounds when using standard 2.75-inch shells.

Can the capacity of an 18.5-inch shotgun be increased?

Yes, the unused space in the magazine tube of many 18.5-inch shotguns can often be utilized. By extending the magazine tube to be flush with the muzzle, capacity can be increased, potentially adding another round.
