Mossberg 509R Standoff Pump-Action Shotgun, 18.5″ Barrel, 50756

Product Description

The Mossberg 509R Standoff is a pump-action shotgun with an 18.5″ barrel and a capacity of 6+1 rounds. You work the action by hand for every shot, which keeps the gun simple to run.

The 18.5″ barrel is the first thing to look at. A shorter barrel is easier to turn in tight spaces, like a hallway or a truck cab. The 6+1 capacity gives you six rounds in the magazine and one in the chamber before you reload.

Who it suits

This shotgun fits someone who wants a pump gun with a short barrel and solid capacity. That could be a home-defense setup, a ranch or property gun, or a range gun for practice with a pump action. Pump guns reward repetition, so plan on some time at the range to build a steady rhythm on the slide.

Good gear to pair with it includes a sling, a side-saddle or butt-cuff shell carrier, and a padded case for transport. Add eye and ear protection for every session, and a cleaning kit sized for your barrel. Buy ammunition that matches the markings on the barrel, and check the owner’s manual for which loads the gun is meant to run.
