There has only been one issue of All-New Captain America. The next and second one comes out on December 10. It's impossible it had been 6, considering the 5th issue doesn't even have a solicitation.

Sam was trained by Captain America. He might not be a soldier, but he was apt for the role of Captain America.

Also, it couldn't have been Patriot, as he's retired.

It was probably made an issue when Bucky took over, but before and after that, regular people were able to wield it. Pretty much like Hawkeye said, it's about balance, not weight. Sam has been stated to have trained to wield the shield (in Captain America and the Mighty Avengers #1).
