TMZ Sports has obtained surveillance video of the moment NFL D-lineman Darius Philon allegedly pulled a gun on women in a strip club parking lot ... but it's unclear if the guy ever committed the crime.
Earlier this summer ... a woman accused Philon -- a 25-year-old who was playing for the Arizona Cardinals at the time -- of threatening to shoot her and her friend in a strip club parking lot.
In the police report, obtained by TMZ Sports, the woman alleges that on May 17 ... she was dancing at V-Live in Phoenix, Arizona when Darius asked her and her friend to come to his car so he could pay her.
She alleges that when they got to his car ... he pulled a gun on them, pointed it at their chests and said, "Which one of you wants a bullet?"
She says when she told him to put the gun down and went to the other side of her friend ... he pointed the gun at her a second time.
In the surveillance video ... you can see Philon clearly speaking with the two women -- but it's difficult to tell if he ever brandishes a weapon.
Cops launched an investigation ... and eventually arrested Philon on Aug. 9 -- booking the 6-foot-1, 286-pounder for aggravated assault with a deadly weapon.
But, Philon is still waiting to receive formal charges in the case ... a rep for the Maricopa County Attorney's office tells us, "We received the case for review less than a week ago and are currently reviewing it for a charging decision."
Philon -- who's still an NFL free agent searching for another team -- signed a 2-year deal worth $10 MILLION with the Cards just months before his August release.
In his 4-year career, Philon has started 19 games and piled up 9.5 sacks.
