“The First Division is the highest level I’ll have played at, so I’ll be able to test myself, and I’ll still train every day at St Mirren.”
McGinn is confident he can help Dumbarton retain their place in the First Division.
He added: “One of my friends is a Sons fan and says they’ve been like a different team since Ian Murray became manager.
“Hopefully, I can help them to continue their recent improvement and force myself into the first team picture at St Mirren.”
McGinn’s younger brother John is currently making a name for himself in the St Mirren team – and the older sibling hopes to go on to make a similar impact at the Paisley club.
“I suppose there was a bit of envy when I sat watching John play in the League Cup semi-final against Celtic,” said McGinn. “I was really pleased for him though and I hope St Mirren win the final against Hearts next month.”
McGinn made his Dumbarton debut in Saturday’s 4-3 defeat at home to Livingston, back in the area where he grew up playing youth football.
He explained: “I played football at the Meadow Centre when I was a boy and had several games for Glen Lusset FC in and around Dumbarton.
“I had many great years at Queen’s Park. Apart from Rangers, Queen’s are the best footballing team in the Third Division and I’m confident they’ll push for promotion through the play-offs.”
Reflecting on Dumbarton’s weekend defeat, McGinn added: “I didn’t think there was much between the teams on Saturday but you can’t give Livingston sloppy goals the way we did.
“I enjoyed getting my first game at this level under my belt and, the more games I get, the better I will adapt.”
