Shortly afterwards, MaGowan switched to the PDC and in his first tournament, he reached the semi-finals of the UK Open Scottish Regional Final.
A quarter final in the 2003 Eastbourne Pro followed and MaGowan played in the 2003 UK Open where he entered the third round outright but lost to Wayne Jones.
MaGowan qualified for the 2005 World Grand Prix and beat Alan Caves and then Peter Manley to reach the quarter-finals.
The run though was temporarily halted when he and his wife Maggie travelled to his son's wedding by helicopter before returning to the Citywest Hotel for his quarter-final game with Dennis Smith, which he lost 4–0.
[1] He has not played in any PDC tournaments since, and at the 2011 World Grand Prix, commentator John Gwynne suggested that MaGowan had retired from professional darts.
