Owners of the Iver Johnson 500 in 20 Gauge frequently mention the black walnut stock as the primary reason for choosing this model. Wood-stocked semi-automatic shotguns are less common at budget price points, and the 500 fills that gap.

The 26-inch barrel suits field use, and the 20 Gauge chambering keeps recoil manageable for extended sessions. Cycling consistency gets mixed feedback, with some owners running it without issues and others noting that lighter loads cause occasional cycling problems until the gun is broken in.

Trigger quality and overall fit-and-finish draw the most criticism. Buyers who set expectations for the price tier tend to rate the 500 positively, while those expecting premium tolerances come away disappointed.
