Detailed Features 

 
The 28-inch vented rib barrel aids target tracking and dissipates heat. The engraved receiver and gold-plated trigger are decorative touches that elevate the appearance beyond a plain utility gun. Five chokes (Full, Improved Cylinder, Improved Modified, Modified, and Skeet) cover upland hunting and clay shooting without additional purchases. The dual trigger system gives you direct barrel selection rather than a single selective trigger, which some shooters prefer for its simplicity and mechanical reliability. Tang safety is positioned where thumb access is natural. 
 
At 7.10 lbs. for a 28-gauge, this gun sits on the heavier side for the gauge, which can smooth perceived recoil. 
 

Usage Scenarios 

• Upland bird hunting where the 28-gauge caliber is appropriate and the gun's aesthetics suit a collector or style-conscious buyer. 
• Clay shooting including sporting clays with choke swaps and skeet with the included SK choke. 
• Collection use given the engraved receiver and walnut/gold trigger combination.

The IJ600 in 28 gauge draws buyers who want an over-under with traditional aesthetics (walnut, engraving, gold trigger) without paying over-under prices from Italian or Belgian makers. The walnut stock and engraved receiver are the two most-praised elements; the gun photographs and handles well.

Feedback on performance is generally positive. Owners report smooth operation and reliable cycling, and the 28 gauge's manageable recoil is specifically noted as a positive for extended shooting sessions. The dual trigger setup is liked by shooters who prefer the tactile simplicity of separate triggers for each barrel.

Critique focuses on price relative to the market and occasional parts availability concerns. The IJ600 is priced as a mid-tier gun, and comparisons to Turkish imports at lower prices and European over-unders at higher prices are common. Aftermarket accessories and replacement parts are less readily available than for more widely distributed brands, which a few buyers mention as a long-term consideration.

For an upland hunter or clay shooter who prioritizes aesthetics alongside function and is not looking for a high-volume competition gun, the IJ600 fits the brief.
