Detailed Features 

Dual extractors and positive steel-to-steel lockup keep the action cycling consistently, and twin action bars minimize the binding that plagues cheaper pump guns. The ambidextrous top-tang safety is easy to reach from a standard shooting grip. Accu-set choke tubes are included for the field barrel. The rifled deer barrel gives you a practical slug gun option at whitetail distances with the adjustable rifle sights. Swapping barrels is tool-free. 
 

Target Audience 

The 500 Combo suits hunters who want one gun that covers both upland birds and deer season. The 20-gauge recoil is lighter than a 12-gauge, making it a practical choice for younger hunters or anyone who prefers a lighter-shooting platform. 
 

Usage Scenarios 

• Bird and upland hunting: 26-inch field barrel with Accu-set chokes 
• Deer hunting: 24-inch rifled barrel with adjustable sights for slugs 
• General field use: Mossy Oak camo for concealment across varied terrain

The 500 Combo is well-regarded among hunters who want dual-season utility from one gun. The ability to switch barrels between upland and deer season use without extra cost or a second shotgun is the most commonly praised aspect.

The 20-gauge is consistently noted as a plus for recoil-sensitive shooters, and the Mossy Oak camo is seen as practical rather than decorative. Build quality and reliability get solid reviews; the 500's action has a long track record and few owners report issues.

Weight gets an occasional mention at 7 lbs, and a few users note that some hunters prefer a 12-gauge for more authority at deer ranges. But most buyers consider the combo a good value for what it delivers.
