Owners of the Mossberg 500 Slugster point to the reliability of the 500 platform as the primary reason for buying it. The pump action cycles anything, and the 24-inch barrel with adjustable sights is set up specifically for slug use at hunting distances.

The black synthetic stock holds up well in wet conditions, which matters to deer hunters. A common observation is that the adjustable sights are functional but not precise enough for shooters who want to mount an optic, since the barrel is not drilled and tapped on all variants.

For a dedicated slug gun, the 500 Slugster is widely viewed as a workhorse choice. Hunters who already own other Mossberg 500 guns appreciate the parts compatibility. Those who want a rifled slug barrel sometimes note the smooth bore limits accuracy at longer ranges.
