It happened around 12:30 a.m. Monday on the 2700 block of West Girard Avenue in Brewerytown.
Police say the 50-year-old male victim and 49-year-old female victim were arguing on the block near a 24-hour convenient store.
Another person, described only as a male, soon got involved, police say.
The two males then got into a verbal argument of their own and that's when the shooter fired a gun.
The male victim was struck in the arm and the female victim suffered a graze wound to the thigh.
Both victims were taken to Temple University Hospital for treatment.
No arrests have been made.
