Owners of the Iver Johnson 600 frequently mention the walnut stock as a quality touch at the price point. The 20 gauge over/under layout is popular among upland hunters, and the 26-inch barrels suit most field applications without being unwieldy in tight cover.

The blued finish draws mixed feedback. Owners who prefer a traditional look appreciate the classic appearance, but some note that blued metal requires more maintenance than synthetic or stainless finishes in wet hunting conditions. The 2-round capacity is inherent to the over/under platform and rarely comes up as a criticism.

Value assessment is the most debated aspect. Some buyers see the 600 as a straightforward entry point into over/under shotguns, while others note that comparable options exist from more widely distributed brands at similar price points. Fit and finish consistency is occasionally mentioned as variable between individual units.
