Captain America #34

Captain America #34, published in 2008, marks a pivotal moment as James "Bucky" Barnes officially assumes the mantle of Captain America. Following the death of Steve Rogers, Bucky grapples with the legacy of his best friend while facing the Red Skull's ongoing plot to destabilize America. This issue is highly notable to collectors as it features the first appearance of Bucky Barnes in his iconic Captain America costume, wielding both the shield and a firearm, establishing a darker, more pragmatic Sentinel of Liberty.
