GAME jumped former G-UNIT rapper 40 GLOCC over the weekend, in broad daylight in the middle of a Hollywood street. Game basically started whaling on 40 Glocc, while Glocc just kept trying to get away.

But 40 Glocc claims there was more to it than that...he says he was threatened with a GUN. After the fight, 40 Glocc Tweeted, quote, "{Game} chased me down with a pistol...{N-word} has to have a gun drawn on me."

"Sources close to Game" say he was NOT armed, and that "it was a one-on-one fight."

Despite his accusations, 40 Glocc says he will NOT pursue legal action against Game.
