Frew were 1-0 down at Cliftonhill after Barry Duncan opened the scoring for the hosts.
But McCoist, son of Rangers and Scotland legend Ally, popped up to equalise and then scored a diving header to earn all three points.
The New Western Park outfit move up to 12th with the victory having been on a good run of form of late that has seen them win four of their last six league matches.
Minutes have been hard to come by for McCoist due to the impressive form from Jordan Moore.
But Quigley admits he isn’t far from earning a spot in the starting 11.
Speaking to Gazette Sport, he said: “I didn’t think we played particularly well, it was quite a scrappy game and there wasn’t many chances created for both teams.
“They scored a fantastic free-kick which gave the goalkeeper no chance but we changed shape for the last 20 minutes and put Argyll on to go two up front and he took his two goals brilliantly, I was delighted for him.
“He’s giving me a headache to try and get a game with what he is doing off the bench.
“His two goals were really good with one shifted onto his left foot and then a brilliant finish into the top corner, and the other is typical striker play to get between the two posts then get on the end of a cross.
“He’s been excellent and he just needs to wait for his chance – Jordan has scored ten in 14, so it’s been hard for him to get into the team.
“He’s a totally different player from his dad because he’s big and gets himself about to win headers and roughs defenders up but the second goal was more like his dad with his positioning.”
A trip to Dumfries is on the cards this weekend where Newton Stewart await.
The Creesiders have struggled for form in the Lowland League West with just one win so far this season.
But Quigley knows his side need to be ready.
He explained: “They are only having narrow defeats so it won’t be easy and we’ve got a long journey which isn’t easy to play football after.
“We’ll treat them with every respect because there are no easy games, if you aren’t at it then you can lose three or four goals against any team in the league so we need to prepare properly this week.”
Kick-off at Blairmount Park on Saturday is 3pm.
