Glasgow got their European campaign back on track with a thumping victory over Italians GRAN Parma at Hughenden.
Hefin O'Hare scored three tries for Glasgow
Former rugby league winger Hefin O'Hare scored a hat-tick of tries in the first half, with centre Andrew Henderson also crossing the line.
Jason Tiatia replied for Parma, but Graeme Morrison and Rory Lamont added tries for the home side.
Sam Pinder (2), Steve Swindall and Kevin Tkachuk completed the rout, with Dan Parks kicking the other points.
