After school, Hargis played for the Anderson Packers for three seasons, then split time between the Fort Wayne Pistons and Tri-Cities Blackhawks during his fourth and final year as a professional.[1][5] For the first two years, the Packers were a member of the NBL. In 1949–50, however, they merged into the NBA. As a rookie in 1947–48, Hargis was second on the team in scoring (642 points; 10.9 ppg).[5] In his second season, he scored 444 points (7.8 ppg), and then in his final season with the Packers, Hargis averaged 10.7 ppg while scoring 643 points.[5] In addition to moderate personal success, the Packers also won the NBL championship in Hargis' second year on the team.
In April 1948, Hargis played in final edition of the World Professional Basketball Tournament with the Packers (team finished in third place) and earned "second all-tournament team" honour after scoring 34 points in 3 games.[6][7]
In April 1950, Hargis was drafted by the Fort Wayne Pistons from the Anderson Packers in a dispersal draft because their franchise had folded.[1] After only playing in a handful of games for the Pistons, he was sold in December 1950 to the Tri-Cities Blackhawks.[1] Hargis finished out the rest of the season with them but was not re-signed to any team and never played professionally again.
