The manager was furious with his players for their part in the 1-1 draw in the Scottish Third Division clash, stating that they were "absolutely miles short" of acceptable
The Glasgow club were on track for their first away victory since being demoted to the Scottish Third Division after Andy Little scored his seventh goal of the season, but were denied by a goal from Fraser McLaren before Chris Townsley had an injury-time strike ruled out for the hosts, and McCoist was furious with the performance.
"Outside the game and the draw, I can't tell you how disappointed I am with the overall performance," McCoist told reporters.
"We will go through it again and watch it because that was agony - and I'll make sure they watch it again.
"We don't look confident, that's for sure. There are a lot of aspects of the overall play that we are far from happy with.
"It was pretty clear to me, there looked to be a lack of confidence throughout the team and that has to be a big concern.
"We could have lost it. I've not seen the disallowed goal at the end but I was obviously just pleased to see it being disallowed.
"Brechin was a jolt, Peterhead was a jolt, Falkirk gave us a right good game. I don't know how many jolts we are wanting."
